What is GPU optical film?
Time：2022-03-28
GPU (Gel Polyurethane) shape memory elastic gel+polyurethane optical film
GPU is a polyurethane optical film material added with shape memory elastic gel. Different from conventional TPU, GPU has more excellent mechanical strength, optical performance, weather resistance and excellent shape memory function.
The excellent shape memory function benefits from the chimeric grafting of a certain amount of self synthesized elastic gel ingredients in the polyurethane structural network unit. Elastic gel can bring many unexpected excellent properties for materials by virtue of its multifunctional reactivity, excellent freedom of chemical structure design, and precise control from synthesis and process end to end.
