PI description
PI properties:
Polyimide is a kind of Heteroaromatic polymers,whose Molecular structure containing polyimide-based monomeric unit.It is a super-performancde Engineering Plastic (250 degree heat can be a long-term job),and has an excellent mechnical and thermal dimensional stability,dielectric properties, wear-resistant,weather resistance,permeability wave,self-lubricating properties,and non-toxic,flame retardant,high temperature sterilization available.
The typical profermance of PI for each grade:
