(acetal copolymer)
Download Product Brochure (21kb - pdf) 

Medical grade Pomalux B 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 B 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 B include EtO gas and steam autoclaving. Disinfectants and germicides generally have no effect on Pomalux B, however, acidic solutions can degrade the polymer.

The following physical property information is based on typical values of the base acetal copolymer resin.
