产品说明

 

AC90MC25L is an acetal copolymer reinforced with 25% mineral, coupled to achieve optimum adhesion at the mineral/polymer interface. This results in improved rigidity, maintained even at higher temperatures, combined with good practical toughness. Although parts molded from acetal copolymer are recognized for exhibiting excellent dimensional stability, incorporation of mineral further improves stability over a broad temperature range. Further, due to the almost isotropic shrinkage characteristics, this compound exhibits very low warpage.

 

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.

 

Typical of acetal copolymer, AC90MC25L 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.

 

AC90MC25L 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 minimum warpage, especially in large area or complex shape parts.
