产品说明

AC90MC10L is an acetal copolymer reinforced with 10% mineral, coupled to achieve optimum adhesion of the reinforcement at the mineral/polymer interface. This results in improved rigidity, especially at higher temperatures, combined with good practical toughness. Further, due to ists almost isotropic shrinkage, this compound exhibits reduced warpage characteristics. Although parts molded from acetal copolymer are recognized for exhibiting excellent dimensional stability, incorporation of mineral also improves dimensional stability over a broad temperature range.

Acetal copolymer is a highly crystalline engineering thermoplastic based on trioxane, polymerized with a comonomer to provide exceptional thermal stability both in processing and for molded parts which may be exposed to high temperature environments.

As with AC90 the base polymer, AC90MC10L exhibits excellent friction and wear characteristics, resistance to the effects of a broad range of chemicals, oils, solvents and greases, and very low moisture absorption.

AC90MC10L should be considered for applications where the fundamental benefits of using acetal are required, combined with improved rigidity, especially at higher temperature, dimensional stability, and reduced warpage, especially in large area or complex shape parts.
