聚醚酮 POLYMER G22 VICTREX HT G45

 High performance thermoplastic material, unreinforced PolyEtherKetone (PEK), semi crystalline, depth filtered granules for injection moulding, low flow, colour natural/beige.

Applications for high strength and stiffness as well as good ductility at higher temperatures. Chemically resistant to aggressive environments, suitable for sterilisation for medical and food contact applications.

聚醚酮（PEK）是以二氟二苯甲酮和对苯二酚为原料高温缩聚形成的特种工程塑料，其主链由醚键和酮键交替构成。材料具有320℃高温蒸气耐受性、15.6 GPa弹性模量等优异力学性能，以及FDA认证级生物相容性。应用涵盖电子电器部件、汽车配件及生物医学植入体，但受制于合成条件苛刻与加工难度大，需通过开发杂萘联苯聚醚酮（PPEK）等衍生物降低生产成本。
