Product Name:Polyoxymethylene (POM) Homopolymer
English Name:Polyoxymethylene (POM) Homopolymer
CAS No.:30525-89-4
Aliases:Polyacetal, Polyformaldehyde, POM Homopolymer
Molecular Formula:(CH2O)n
Physical Properties:POM homopolymer is an opaque crystalline thermoplastic resin with a density of approximately 1.42 g/cm³ and a melting point of about 175°C. It exhibits excellent mechanical strength, rigidity, and wear resistance, low water absorption (0.25% after 24-hour immersion), outstanding fatigue resistance, and good electrical insulation. Its performance remains stable over a wide temperature range from -55°C to 122°C.
Uses:Widely used in automotive components and power tool parts, as well as for manufacturing precision gears, bearings, valves, pump bodies, and other mechanical parts requiring high rigidity and wear resistance.
Technical Specifications:
Density: 1.42 g/cm³ (ASTM D-792)
Tensile strength at 23°C: 69 MPa (ASTM D-638)
Flexural modulus at 23°C: 3090 MPa (ASTM D-790)
Heat deflection temperature at 1.8 MPa: 136°C (ASTM D-648)
Volume resistivity: 1×10^15 Ω·cm (ASTM D-257)
