POM HENGLI HLMC90
HENGLI POM HLMC90 – standard-flow acetal (POM) copolymer for precision injection parts (gears, pumps/valves, bearings, cams); high fatigue & creep resistance with good electrical properties
Sold by container only: 22.25 mt/container. Quantity = number of containers.
Key Benefits
Standard flow (MFR 9 ± 1 g/10 min) – clean filling of tight-tolerance, thin-wall moulds.
Strong & stiff – yield stress ≥60 MPa, tensile modulus ≥2500 MPa for durable parts.
Impact capable – Charpy notched ≥6.0 kJ/m² @ 23 °C limits cracking in service.
Thermal performance – HDT (1.8 MPa) ≥85 °C supports warm-service loads.
Dimensional/electrical stability – density 1.38–1.43 g/cm³; low surface aldehydes (≤100 mg/kg).
