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.
