Acetal manufactured by Quadrant EPP
is branded ERTACETAL®. Acetal resins are crystalline
thermoplastic polymers with a melting point somewhat
lower than nylon. Valuable mechanical properties include
high strength and stiffness as well as good wear and
impact resistance. Acetal's low water absorption results
in excellent dimensional stability even in high moisture
environments.
There are two types of a Acetal:
homopolymer (H) and coploymer (C). The homopolymer DELRIN®
of Du Pont and the copolymers of Hostaform of
Hoechst and Ultraform of BASF are the most commonly used
trade marks in Europe.

Both homopolymer (DELRIN®) and copolymer grades are similar in
their overall balance of properties although each shows
some difference from the other in detail. In general,
the mechanical properties of the homopolymer (DELRIN®) are
slightly superior to the copolymer although the latter
has a higher continuous operating temperature. Alkali
resistance of the copolymer is superior to that of the
homopolymer (DELRIN®)and it is not effected by long term exposure
to water even, at temperatures of 60 to 90oC.
This can cause some reduction in properties of the
homopolymer (DELRIN®) material.
