IR Blocking Film
WeeTect IR Blocking Film (WIRBF) also names heat resistant 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 IR transparent plastic film for IR filter and IR reflective features.
WeeTect IR Blocking Film (WIRBF) offers excellent infrared blocking, UV blocking and abrasion resistant properties as well as optical clarity, impact resistance, and dimensional stability. Compare with other IR blocking film suppliers, WeeTect IR Blocking Film (WIRBF) performs better UV/IR and abrasion resistance. A perfect match for all car and residential windows, the IR blocking film sustainable performance lasts long in order to protect users consistently.
