Polynaphthylbiphenyl polyetherketone (PPEK) is a high-performance special engineering plastic with good market development prospects.

Phenylbiphenyl polyetherketone (PPEK) is a new type of special engineering plastic made on the basis of polyetherketone (PEK). Polyetherketone (PEK) is a high molecular polymer whose main chain is formed by alternating ether bonds and ketone bonds. Polyaryl ether ketone is a typical product, using difluorobenzophenone and hydroquinone as raw materials. Made by polycondensation under…
