产品说明

AC90GR25WL is an acetal copolymer reinforced with 25% glass fiber, coupled to achieve optimum adhesion at the glass fiber/polymer interface, and UV stabilizers added to the compound to improve its resistance to weathering. 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, AC90GR25WL exhibits excellent resistance to the effects of a broad range of chemicals, oils, solvents and greases, as well as very low moisture absorption.

AC90GR25WL should be considered for applications, that require resistance to UV exposure and need strength and rigidity, especially at high temperature.
