Polycarbonate lamination is a popular plastic fabrication technique that plays a critical role in industries.
Through lamination, you will make polycarbonate sheet more functional, with superior properties.
But, how can you achieve this?
Today’s guide takes you through all the details of polycarbonate lamination – from benefits, classification, considerations, common problems, buying lamination machine, etc.
Now, let’s dive right in.
What is Polycarbonate Laminating?
This refers to the process or technique of manufacturing a polycarbonate sheet by bonding layers of the material together.
It is a crucial process which requires quite a lot of knowledge and often takes place in well-equipped laboratories.
The essence of undertaking this procedure is always to enable the sheet to attain the necessary stability, and strength.
In other instances, the purpose of this technique could also be to allow the material to attain sound insulation and ideal appearance among others.
Ordinarily, polycarbonate laminating often happens through heating or by using adhesives.
It all depends on the type of laminate you are using.
And that is why in many instances you’ll realize that polycarbonate laminating can be put together by either cohesion or adhesion.
If you’re keen enough, you’ll notice that polycarbonate laminates are often various layers materials that are held together by a plastic material.
What’s more is that the only way to distinguish a laminated polycarbonate is by understanding that they are made of layers of material.
So that’s primarily what polycarbonate laminating is all about.
However, before we continue, let’s first find out some of the reasons why this technique could be essential.
Why Laminate Polycarbonate?
Of course, this is one of the most critical technique to undertake.
Therefore, you got to have all the reasons for doing it before even thinking of how to start it.
Different people often laminate polycarbonate or rather go for laminated polycarbonate materials for numerous reasons.
In this section, I want us to look at some of the key reasons for laminating this particular type of plastic material.
Some of such reasons include the following;
· To easily combine characteristics of several materials in a single pane
Well, this is one of the key reasons why many people often undertake the process of laminating polycarbonate materials.
You see, in many instances, you’ll find that your application requires the final product to attain some particular properties.
These characteristics may vary from one application to the other.
And some of them may include resistance, anti-glare, anti-reflection and anti-scratch properties among others.
Scratch-resistant polycarbonate sheet
But then, incorporating such properties especially on finished product can tend to be relatively difficult.
So one of the easiest ways that you can use of course is by laminating the different materials in a single pane.
In many instances, this becomes a success, and the end product attains all the necessary characteristics through lamination.
· To enhance the resistance of the material to breakage
It is also another reason why laminating polycarbonate would be essential.
Well, we all know that polycarbonate is one of the most robust materials you can ever get around.
And it is the main reason nowadays; it’s used in almost different relevant applications.
But then, the strength might be relative.
And in some instances, the strength has to be extreme as a way of sustaining particular projects or applications.
Laminating this material is an ideal way of improving its resistance to breakage.
Of course while at it, you have to use different ingredients for the material to achieve this characteristic.
What happens though, is that you have to ensure that the combination of these ingredients is suitable before laminating the sheet.

So the bottom line here is that polycarbonate laminating is essential when it comes to enhancing the resistance of a material to breakage.
And it’s in such instances that you’ll find perhaps the laminate is what breaks but the actual material remains still.
Many people, therefore, deem it ideal to laminate the polycarbonates before using them in various applications due to such characteristic.
· To improve the attractiveness of the finished material
If you’re keen enough, you’ll notice that most of the laminated polycarbonate materials tend to have some appealing features.
What happens is that before laminating, the material is seemingly plain.
And there are specific applications which require more than the basic characteristics of the polycarbonate material such as durability.

So for the sheet to have an attractive look, in some instances, you’ll need to laminate it using specific types of laminates.
So that by the time you complete the process, you’ll be able to have a bright and striking finish that is appealing to the eye.
And in all these, you’ll probably increase the chances of making the material sellable or have high demand in the market.
· To increase clarity of the polycarbonate
This is also the other fundamental reason why you need to or why many people opt for laminating polycarbonate material.
You see, most of the polycarbonate applications are often those that expose it to various physical and environmental hazards.
So other than strength, you also require the sheet to maintain or enhance its clarity, of course depending on the application.
Therefore, laminating helps by providing a protective layer which guarantees the clarity of the material especially those for optical applications.
For example, a vehicle’s windscreen requires a high level of clarity irrespective of the prevailing weather condition.
And when you laminate it, it becomes it increases chances of maintaining the clarity throughout.
The main reason here is that the laminate, which forms the outer layer protects the polycarbonate sheet from a wide range of damaging effects.
It prevents it from scratches, which ordinarily destroys clarity.
It also protects the surface from glare, unreasonable reflection as well as other weather conditions.
· To control extreme weather conditions
In many instances, you’ll notice that several areas all over the world tend to experience different types of extreme weather conditions from time to time.
Using a laminated polycarbonate would be helpful in such instances because it makes it possible for you to control such conditions.
For example, in high temperatures, the laminated polycarbonates can easily cool down the temperatures accordingly.
While on it, this type of technology also helps to prevent other aspects of weather such as glare among others.
The substances for polycarbonate laminating are essential because they also help in enhancing UV resistance.
This, of course, is vital because it allows you and other people to have good health.
· To minimize sound transmission
Another compelling reason why you would need to laminate polycarbonate sheet is to reduce transmission of sound in the vicinity.
You see, there are these establishments in areas that seem to be somehow busy and experience colossal traffic.
For example, the business premises along the busy streets are affected most of the time because of the noise within the surrounding.
Polycarbonate sound barrier
Also, areas like a restaurant and other entertainment joints that play loud music would always want to restrict the noise within the premises.
Now the more relaxed way of attaining this and at the same time maintaining the classy look of the premises is by using laminated polycarbonate.
Most of the substances you use for laminating such sheets prevent excessive noise from getting out or into such establishments.
And this is ideal because, for a restaurant or entertainment joint, it prevents inconveniencing other people within the premises.
So these are some of the key reasons why you would necessarily need to laminate polycarbonate.
Of course, as you may also know, in some instances, you’ll need to laminate polycarbonate for other various reasons.
In fact, it’s a particular application that determines the necessity of laminating a polycarbonate material.
In the next section though, I want us to look at the major types of laminating polycarbonate material.
Types of Polycarbonate Laminating Techniques
The truth of the matter is that laminating polycarbonate is one of the most sophisticated processes you can ever think of.
You see, what happens is that you have to use the best technique to ensure that you obtain the best results from this process.
Types of polycarbonate techniques also tend to vary depending on one application to the other.
However, in this section, we want to look at the two major types of undertaking this technique.
The significance of this is to enable you to know them in details and to give you an idea of what to expect.
So let’s go straightaway and discuss more these two major types;
1. Polyvinyl butyl polycarbonate lamination
Well, this is arguably one of the most common and preferable kinds of laminating polycarbonate technique.
In many instances, you’ll find it referred as PVB, and it is common in polycarbonate applications which require optical clarity and strong binding.
PVB is also ideal for laminating applications that require adhesion to several surfaces, those that need flexibility as well as toughness.
Generally, PVB polycarbonate lamination entails the use of two or more sheets bonded together with one or more layer of PVB ingredient.
So it happens that you sandwich the PVB layer between the glazing sheets.
In that process, you’ll need to use somewhat sophisticated equipment where the assembly shall pass through nip rollers to expel air bubbles.
The essence in such instances is to ensure that there is ideal contact between the layers.
This type of lamination, in general, integrates several elements of PVB ingredients with the layers of the polycarbonate sheet to form a strong bond.
And by the end of the process, you’ll have a laminated polycarbonate that is strong and adheres to the interlayer.
The benefit of using this technique is that the interlayer functions to hand out impact forces through a greater area of polycarbonate pane.
Secondly, the interlayer also functions to bind the resultant shard should the polycarbonate material end up breaking.
And lastly, the interlayer, which apparently is viscoelastic goes through plastic deformation during impact hence absorbing energy.
2. Resin polycarbonate lamination
This is also the other common type of lamination technique for most of polycarbonates sheets.
Ideally, it involves the use of a resin substance which is a solid or somewhat viscous element of a plant that is convertible into polymers.
The design of this substance is to allow it to remain clear even when catalyzed.
Laminating polycarbonate using a resin also has an adhesion promoter which apparently dormant until the catalyst’s adhesion.
You also need to know that this adhesive is a specially adapted.
The use of resin to laminate polycarbonate is vital because if a wide range of reasons;
First is that this substance tends to hold reinforcement material together as it allows it to conform to the desired shape.
This substance also helps to transfer mechanical properties from fiber bundles across the entire part.
One of the key properties of this substance is that it has an excellent viscosity which makes it easy to use and allowing fast air bubble release.
The other good thing with resin polycarbonate lamination is that it enables you to laminate the sheets at cost-effective rates.
And by the way, you do not need expensive machinery to produce laminated polycarbonate using this particular technique.
The other good thing with resin polycarbonate lamination is that it can protect the sheet from bad weather and other natural disasters.
Well, and that could be the reason this particular type of lamination is preferred for application in areas that experience extreme weather conditions.
Common Problems in Polycarbonate Laminating Process
Listen, like I did mention before, laminating is a technique that requires quite a lot of experience and knowledge.
But that notwithstanding, in most instances, several challenges tend to arise whenever you’re laminating polycarbonate.
Of course, it depends on quite a lot of factors because every problem possibly arises due to different aspects.

Therefore, whenever you’re laminating this material, you need to be observant of the bubbling issue and try to avoid it as much as possible.
The most common cause of wrinkling issue is insufficient supply roll tension.
What often happens is that each laminator requires a particular amount of resistance to the unwinding supply of the rolls.
In most instances, when you’re laminating thinner polycarbonate sheets, you’ll need less tension.
And thicker films will require more tension.
c) Orange peel
This refers to the extremely fine wrinkles or waves that you’re likely to find in the laminate.
In most instances, the cause of this effects is always used of excessive heat when laminating polycarbonate.
What you need in this instance to avoid such effects is merely adjusting the temperature to an ideal setting.
You also need to know that orange peel can as well arise as a result of laminating sheets with a lot of solvent residues.
d) Waving, blistering and dimpling
The main cause of these effects is the presence of natural moisture in the material which makes the item to swell closer to the laminate.
Using too much heat dries out the moisture, but swollen areas distort the material from lying flat.
Insufficient tension, as well as uneven pressure, can also lead occurrence of such effects during the laminating process.
e) Static electricity
It is also a common issue that is likely to arise as you laminate polycarbonate.
At times, it could be difficult to prevent it, but you can easily keep it under control by taking different precautions.
And it is a significant problem, especially when laminating lighter polycarbonate sheets. So you have to devise methods of alleviating this problem effectively.
One tip of preventing this challenge is removing or neutralizing it by induction.
The other precautionary method is by grounding all your plant machinery and other related equipment.
The essence of this is to help in draining off extremely high static electricity charges on both sides of static-laden material.
f) Repeating marks
Well, this is always a major problem that arises typically when there is something on the roll.
That something could be an object such as a piece of paper, or in other instances, a scrap of film.
So an ideal way of dealing with this is by cleaning the rolls appropriately to remove such residues.
In the next section, we want to look at some of the fundamental elements that you need to consider when laminating polycarbonate material.
