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.
