Product Name:Polyoxymethylene M270-44
English Name:Polyoxymethylene M270-44
CAS No.:9002-81-7
Aliases:POM, Polyacetal, Acetal resin
Molecular Formula:(CH2O)n
Physical Properties:Density 1.41 g/cm³, water absorption 0.5% (24 h immersion in water at 23°C), stable performance across a wide temperature range from -40°C to 100°C. Highly crystalline acetal copolymer with high strength, rigidity, good wear resistance and self-lubrication, and excellent fatigue resistance. Resistant to fuels, oils, organic solvents, weak acids and weak alkalis, but strong acids and phenols should be avoided. Complies with REACH SVHC, RoHS, FDA, NSF, EN1186 standards.
Uses:Used in automotive components such as fuel pump modules, transmission gears and seat belt buckles requiring oil and wear resistance; precision parts in electronics and electrical appliances including printer gears, switch connectors and precision bearings; conveyor components, valve seals and high-rigidity structural parts in industrial equipment; and consumer products such as zippers, toy accessories, fitness equipment and outdoor sporting goods.
Technical Specifications:
Tensile strength: 88 MPa; flexural strength: 88 MPa; flexural modulus: 2550 MPa; elastic modulus: 2800 MPa.
Dynamic friction coefficient (vs steel): 0.37; wear factor: <1.0×10⁻³ mm³/(N·m).
