POM FORMOSA FM270
FORMOCON® FM270 – high-flow acetal (POM) copolymer for precision injection parts (zippers, electronic parts, press-in fasteners, gears); UL 94 HB.
Sold by container only: 20.00 mt/container. Quantity = number of containers.
Key Benefits
High flow rate (MFR 27 g/10 min @ 190 °C / 2.16 kg) – fills thin, tight-tolerance moulds cleanly.
Balanced strength & stiffness – tensile yield ~60.8 MPa; flexural ~93.2 MPa for durable parts.
Dimensional stability – low water absorption (0.22% @ 23 °C/69% RH) with controlled shrinkage 1.8–2.2%.
Electrical insulation – dielectric strength ~24 kV/mm; high surface/volume resistivity.
Thermal robustness – HDT 158 °C (0.45 MPa) / 110 °C (1.82 MPa); Vicat ~162 °C; Tm ~165 °C.
