Product Name:Polyoxymethylene K90
English Name:Polyoxymethylene K90
CAS No.:9002-81-7
Aliases:Polyacetal resin, Polyoxymethylene, Acetal resin
Molecular Formula:(CH2O)n
Physical Properties:POM K90 is a low-viscosity polyoxymethylene resin with excellent flowability and good processability. It has a density of 1.41 g/cm³, melt flow rate (190°C/2.16 kg) of 42 g/10 min, mold shrinkage of 2.0%, and water absorption (equilibrium, 23°C, 60% RH) of 0.22%. Tensile strength (yield) is 64.0 MPa, flexural modulus is 2700 MPa, and Izod notched impact strength is 50 J/m. Heat deflection temperature (0.45 MPa) is 158°C, Vicat softening temperature is 162°C, and melting temperature is 166°C. Surface resistivity is 1.0E+16 ohms, volume resistivity is 1.0E+14 ohms·cm, and dielectric strength is 19 kV/mm. UL flammability rating is HB.
Uses:Mainly used for injection molding, suitable for thin-wall parts, precision gears, and sliding parts. This grade features low viscosity and excellent flowability, making it particularly suitable for filling complex molds and widely used in electronic appliances, automotive parts, and mechanical components.
