Features：
Adding the red high temperature resistant pigment into the polyamide acid to form a film, the overall appearance of red, uniform color distribution. It has the same property as CN type, heating-resistant, radiation resistant, stable chemical reaction. We can supply 25um and 50um thickness.
Size：
1、Thickness：25μm、50μm、75μm.
2、Width：520mm.
