Polyimide is an aromatic heterocyclic polymer compound whose molecular structure contains an imide group chain. The English name is Polyimide, and is abbreviated as PI. Its density is 1.35, non-toxic, flame retardant, and can be used for high temperature sterilization. Polyimide (PI) is a super engineering plastic with excellent comprehensive performance (250 degree high temperature can work for a long time), and has excellent mechanical properties, thermal dimensional stability, dielectric properties, wear resistance, weather resistance, Permeability, self-lubrication, and other properties are called "problem solvers."
