Implantation - Import export

Medical grade Lennite UHMWPE is produced from premium resins im accordance with ASTM specification F648 and International Standard ISO 5834-1 for surgical implants. Westlake Plastics' proprietary manufacturing processes and stringent quality control permit a well consolidated and consistent fabricated form. Recommended sterilization techniques include EtO gas, cold sterilization, and limited gamma irradiation. Often used for total hip and knee joint prosthesis, various other surgical implants and medical devices.

Westlake Plastics manufactures medical grade polymer stock shapes in rods and sheets for orthopaedic trial parts and instruments, dental applications and other surgical tools and accessories requiring medical grade standards and biocompatibility. Within its range of medical grade polymers, Westlake offers: - Polycarbonate (PC) gamma sterilized under its Zelux® GS brand name - Polyetherimid (PEI) under its Tempalux® brand name - Polypropylen (PP) under its Propylux® brand name - Polyphenylsulfon (PPSU) under the Radel® brand name - Ultra High-Molecular Weight Polethylen (UHMW-PE) under its Lennite® brand name These polymers can be used for various medical and surgical tools, knee / hip / shoulder trial parts for orthopaedic implant kits and various other medical grade applications (sterilizable cases and containers) requiring high biocompatibility specifications (USP Class VI and ISO10993).

With the new tightening procedures for cleaning and disinfecting implant ancillaries, PPSU offers an interesting solution guaranteeing a longer life cycle for products. Though it costs usually more than other medical grade polymers (POM, PP), it can nevertheless prove to be more economical in the long term due to its durability. This is especially true for complex designs which are expensive to machine. PPSU does not have any problems with the cleaning & pre-disinfection products. Our material is lot controlled, serialized and is delivered with a certificate of conformance. Coloured resin has been tested under ISO10993/5/10/11/18. The material is not for permanent implantation. PPSU behaves very well after a large number of sterilisation cycles in an autoclave at 134°C/273°F, it can be sterilized through other methods (ETO; gamma, plasma, dry heat). it is polishable for a perfect finish.
