Low water absorption rate: only about 30% of PA6, stable in size and not easily deformed in wet state.
Low temperature resistance: maintains high toughness at -60 ℃ without brittle cracking.
Oil resistance: resistant to fuel, lubricating oil, hydraulic oil, suitable for automotive/industrial oil circuits.
Wear resistant and self-lubricating: suitable for dynamic friction parts such as gears, bearings, sliders, etc.
Electrical insulation: low dielectric constant, low loss, suitable for electronic/high-frequency components.
Lightweight: Density of about 1.08 g/cm ³, 10%~12% lighter than PA66.
