Product Name:Acetal Copolymer (POM)
English Name:Acetal Copolymer (POM)
CAS No.:9002-81-7
Aliases:POM copolymer, Polyoxymethylene copolymer, Polyacetal copolymer
Molecular Formula:(CH2O)n
Physical Properties:It has a highly crystalline linear structure with excellent overall performance. Density is about 1.41 g/cm³, melting point is about 160–175°C, heat deflection temperature (0.45 MPa) is about 110°C, and water absorption is low. It exhibits excellent wear resistance, long-term fatigue resistance, toughness, and creep resistance, as well as outstanding resistance to moisture, solvents, and strong alkalis. Compared with acetal homopolymer, the copolymer structure offers higher stability against thermal and oxidative degradation.
Uses:Suitable for general-purpose injection molding and extrusion of films. It is widely used to manufacture precision gears, bearings, automotive parts, electronic and electrical components, industrial parts, and packaging films, performing excellently in applications requiring high rigidity, dimensional stability, and wear resistance.
Technical Specifications:
Melt mass-flow rate (190°C, 2.16 kg) is about 9 g/10 min (M90 grade).
Density is about 1.41 g/cm³.
Melting point is about 160–175°C.
Tensile yield strength is about 65 MPa.
Flexural modulus is about 2,600 MPa.
