Description
PEKK is a high-performance thermoplastic polyether ketone. Its chemical backbone exhibits high stability. The semi-crystalline structure of the material offers outstanding mechanical and thermal durability, along with chemical and fire resistance in its solid form. The performance of PEKK varies depending on the type of monomer acid chloride used. When synthesized using terephthaloyl chloride, PEKK achieves the highest glass transition temperature and melting point relative to other typical polyarylether ketone types. PEKK is produced with isophthaloyl chloride as the raw material exhibits lower melting and glass transition temperatures. In practice, PEKK is typically synthesized from a blend of terephthaloyl chloride and isophthaloyl chloride.
