POM YUNTIANHUA M270
YUNTIANHUA® M270 – high-flow acetal (POM) copolymer for thin-wall, precision injection moulding (lighters, aerosol bottles, fasteners); UL 94 HB.
Sold by container only: 23.00 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 mechanics – tensile yield 62 MPa; flexural 89 MPa; modulus ~2550–2700 MPa for durable parts.
Dimensional stability – low warpage, low friction; good chemical & solvent resistance.
Impact performance – Charpy notched 5.0 kJ/m² @ 23 °C limits cracking in service.
Processing friendly – minimised mould deposit; designed for injection moulding.
