Product Name:Polyoxymethylene (POM) N2320 003
English Name:Polyoxymethylene (POM) N2320 003
CAS No.:9002-81-7
Aliases:Polyacetal, Acetal resin, Polyformaldehyde
Molecular Formula:(CH2O)n
Physical Properties:Density 1.42 g/cm³, specific gravity 1.41-1.43 g/cm³; melting point approx. 175°C, high crystallinity; good thermal stability (copolymer POM), wide processing temperature range (approx. 50°C), good resistance to acids and alkalis; high strength, excellent wear resistance; molding shrinkage 1.2-3.0%, water absorption 0.22-0.25%; long-term heat resistance -40~100°C, decomposition temperature 240°C, heat distortion temperature 172°C; low friction coefficient, good electrical insulation, high dielectric strength; good solvent resistance to hydrocarbons, alcohols, aldehydes, ethers, gasoline, lubricating oils and weak bases; poor weather resistance, prone to chalking and cracking under long-term UV exposure.
Uses:Suitable for injection molding of general-purpose products, automotive parts, household appliance parts, and thin-wall products. The material offers high strength and wear resistance, providing good dimensional stability and fatigue resistance.
Technical Specifications:
Density: 1.42 g/cm³, specific gravity 1.41-1.43 g/cm³.
Processing temperature: 170-200°C; drying conditions: 80-90°C for 2 hours.
Molding shrinkage: 1.2-3.0%.
Heat distortion temperature: 172°C; long-term heat resistance: -40~100°C.
Water absorption: 0.22-0.25%; dielectric strength (0.127 mm thickness): 82.7 kV/mm.
