Product Description
AC90GR25 is an acetal copolymer reinforced with 25% glass fiber, coupled to achieve optimum adhesion at the glass fiber/polymer interface. This results in outstanding strength and rigidity, maintained even at higher temperatures, combined with excellent practical toughness. Incorporation of glass fiber also further 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, AC90GR25 exhibits excellent resistance to the effects of a broad range of chemicals, oils, solvents and greases, as well as very low moisture absorption.

AC90GR25 should be considered for applications which require the fundamental benefits of acetal combined with the strength and rigidity, especially at high temperature, and dimensional stability benefits of this reinforced compound.
