Product Description
TECAFORM AH natural acetal is an unfilled porosity free POM-C with a unique balance of physical properties not available in most other thermoplastics. This copolymer acetal is an engineering plastic made for wide-ranging universal applications in many different industries. The key performance characteristics of unmodified POM copolymer include high mechanical strength and rigidity, excellent wear, low moisture absorption and excellent dimensional stability. Unfilled POM-C copolymer is manufactured by Ensinger under the tradename TECAFORM AH natural, and offers high crystallinity and a good degree of toughness (even in the lower temperature range), combined with good chemical resistance.
