Hanyao quality Electrical insulation aramid paper is not the ordinary paper we use for writing or printing in our daily lives, but a high-tech material that combines the thinness and flexibility of paper with the high strength, high temperature resistance, and flame retardancy of engineering plastics and even metals.a calendered paper, offers excellent dielectric strength, mechanical properties, flexibility and resilience. There are 9 thicknesses, from 2 mil to 30 mil (0.05mm to 0.76mm). It is used in almost every known electrical sheet insulation applications.
It has high temperature resistance and can offer short-term overloading.Its most outstanding characteristic is that it can withstand long-term operating temperatures above 200°C, and can withstand short-term high temperatures of 300-400°C without melting or decomposing. It also self-extinguishes after being removed from an open flame and does not support combustion.
Simply put, aramid paper is a high-performance special paper-based material made from aramid fibers through a special papermaking process, possessing excellent properties such as high temperature resistance, flame retardancy, high strength, and insulation.
