Uv Window Film
WeeTect UV Window Film (WUVWF) also names UV blocking window film which is a Nano coated PET film featuring both Ultraviolet (UV) and Infrared (IR) protection screens on the outer layer and an adhesive on the inner layer. It is a specially designed film for laser cutting machine windows and other equipment which need UV blocking and IR blocking film. WeeTect also offers the total solution of UV and IR blocking window with high impact resistant polycarbonate sheet together.
WeeTect UV Window Film (WUVWF) offers excellent UV/IR resistant and abrasion resistant properties as well as optical clarity, impact resistance, and dimensional stability. Compare with other UV window film suppliers, WeeTect UV Window Film (WUVWF) performs better UV/IR and abrasion resistance in blocking laser rays to workers’ eyes. A perfect match for all laser cutting machine windows, the UV window film sustainable performance lasts long in order to protect users consistently.
