Acetal Copolymer (B) Specifications

Description

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

Applications
