Description

Key Benefits

Standard flow (MFI 9 g/10 min @ 190 °C / 2.16 kg) – clean filling of tight-tolerance, thin-walled moulds.
Balanced strength & stiffness – tensile 62 MPa, tensile modulus 2.7 GPa, flexural 87 MPa / 2.5 GPa for durable parts.
Dimensional stability – low water uptake (0.5% / 24 h) and predictable mould shrinkage (2.3% flow / 2.1% transverse).
Low friction & wear – smooth running against metals and plastics for longer life.
Electrical insulation – dielectric strength ~19 kV/mm, volume resistivity ~1×10¹⁴ Ω·cm.
Thermal robustness – HDT 95 °C @ 1.8 MPa for load-bearing performance in warm service.
