TORLON® PAI
The TORLON® PAI grades, is one kind of new acyl engineering plastic. As the molecules of TORLON® PAI, has a rather steady heterocyclic structure inside, which has the excellent performances of intrinsic high and low temperature resistance that other macromolecule materials can’t compare with, and has excellent mechanical strength and dimensional stability resistance. Especially: high temperature resistance,high strength,high insulation,anti-radiation,chemical corrosion-resistance,self-lubrication and extremely low thermal expansion.
