共聚甲醛POM M90-44 CF2001 中粘度 (CAS No.None)

Product Name:Copolymer Acetal POM M90-44 CF2001 Medium Viscosity

English Name:Copolymer Acetal POM M90-44 CF2001 Medium Viscosity

CAS No.:9002-81-7

Aliases:Polyoxymethylene, Polyacetal, POM

Molecular Formula:(CH2O)n

Physical Properties:Copolymer acetal is supplied as milky-white or light-yellow pellets with a density of approximately 1.41 g/cm³ and a melting range of 165–175°C. It exhibits excellent chemical resistance to most inorganic chemicals, oils, hot water, and alkalis, except for strong acids and strong oxidizing agents. The electrical insulation performance is excellent, with dielectric constant and dielectric loss varying little over a wide range of temperature, humidity, and frequency, and arc resistance is outstanding. Molded parts have smooth surfaces, good gloss, high dimensional accuracy, low molding shrinkage, and low water absorption.

Uses:It is widely used in the electrical and electronic field for connectors, switch components, and coil bobbins; in the automotive industry for fuel system parts, interior components, and engine peripheral parts; and in mechanical manufacturing for gears, bearings, and cams, as well as in daily necessities such as zippers, toothbrush handles, and toy parts.
