Lennite Implant Grade
(ultra-high molecular weight polyethylene)
Compression molded medical grade UHMWPE is produced in accordance with ASTM F-648 standards for use as an implant grade material and is ISO 5834-1 and ISO 5834-2 compliant for use in international markets. Westlake compression molded sheets are formed under heat and pressure, and are slowly cooled to produce a very dimensionally stable, virtually stress-free sheet ideal for machining and fabrication. When machining close tolerance parts, a fabricator will experience very little material movement. Our proprietary process provides sheets with inherent stress levels that are extremely low or nonexistent in some cases than those typically found in the same materials that have been extruded and secondarily annealed. Westlake production is performed under clean room conditions in accordance with FDA mandated GMPS. Our quality system is ISO 9001 certified.

MediPEEK-IM
(Polyetheretherketone)
MediPEEK-IM is a high performance semi-crystalline thermoplastic designed for long term body contact as an implantable material. It is USP ClassVI and compliant to ASTM F2026. It has excellent sterilizability asd has been extensively tested to ISO-10993 requirements.

MediPEEK-T
(Polyetheretherketone)
MediPEEK-T is a high performance PEEK semi-crystalline thermoplastic designed for short term body contact as an implantable material. It is USP Class VI and ASTM F2026 compliant. It has excellent sterilizability and has been extensively tested to ISO 10993 requirement for short term implant.

Pomalux®
(acetal copolymer)
Medical grade Pomalux is made from acetal copolymer resin which allows machined products the ability to retain dimensional integrity, maintain stability in water and most chemicals at elevated temperatures. Pomalux products are opaque and are available in a wide array of standard colors as well as on a custom basis. Recommended sterilization techniques for Pomalux include EtO gas and steam autoclaving. Disinfectants and germicides generally have no effect on Pomalux, however, acidic solutions can degrade the polymer.

Propylux® HS
(polypropylene-heat stabilized)
Medical grade Propylux HS is made from an FDA approved polypropylene resin. Through a unique heat-stabilizing process, the extruded material is able to withstand higher temperatures with less water absorption than standard polypropylene. Recommended sterilization techniques for Propylux HS include steam autoclaving and cold sterilization.

Propylux® HS2
(polypropylene-heat stabilized)
Through process improvement and advanced engineering, Westlake Plastics introduces the next generation of heat-stabilized polypropylene. Propylux HS2 is produced from a FDA and USP Class VI approved homopolymer resin, and exhibits better heat and dimensional stability over Propylux HS. Recommended sterilization techniques for Propylux HS2 include steam autoclaving and cold sterilization.

Radel® R5500
(polyphenylsulfone)
Medical grade Radel R5500 resin offers exceptional hydrolytic stability, toughness, and superior impact strength over a wide temperature range. This product also offers high deflection temperatures and outstanding resistance to environmental stress cracking. Recommended sterilization techniques for Radel R5500 include EtO gas, radiation, steam autoclaving, dry heat and cold sterilization.

Tempalux®
(polyetherimide)
Medical grade Tempalux is made from Ultem® polyetherimide resin, an amorphous thermoplastic which exhibits excellent resistance to a wide range of chemicals and disinfectants. Ultem maintains its size and shape over a broad temperature range as well as tolerates a high amount of stress over extended periods of time. Recommended sterilization techniques for Tempalux include EtO gas, radiation, steam autoclaving, dry heat and cold sterilization.

Zelux® GS
(polycarbonate - gamma stabilized)
Medical grade Zelux GS polycarbonate is produced from resin formulated to meet the stringent performance characteristics and requirements of the healthcare industry. Suitable for EtO gas and limited autoclaving sterilization, the resin also has proprietary color enhancement technology to reduce color shift caused by gamma radiation.
