Medical grade Pomalux is made from acetal copolymer resin which allows machined pr

oducts the ability to retain dimensional integrity, maintain stability in water and most ch

emicals at elevated temperatures. Pomalux products are opaque and are available in a w

ide array of standard colors as well as on a custom basis. Recommended sterilization tech

niques for Pomalux include EtO gas and steam autoclaving. Disinfectants and germicides

generally have no effect on Pomalux, however, acidic solutions can degrade the polymer

. Westlake Plastics Company manufactures all acetal extruded & compression molded she

ets, plates and rods in accordance to ASTM D6100. This specification covers requirement

and test methods for the material, dimensions, workmanship and the properties of extrud

ed and compression molded sheets, plates and rods.

Applications Include:

• Provisional trials

• Instrument handles

• Medical device components

• Lot controlled and traceable

• Resin complies with FDA regulations 21 CFR 177.2470 and 21 CFR 178.3297 for colorants

• Resin meets the requirements of USP Class VI specifications

• Stress relieved

• Laser markable
