Key Properties

Similar to Polypropylene but better at at lower temperatures (-50°C to +80°C ) this material has better wear resistance & abrasion resistance. Low Density. Good corrosion resistance, electrical insulation properties. High Yield Point. Stable for machining.


  • Very low cost
  • Excellent chemical resistance
  • Very good processability
  • Good low temperature resistance
  • Excellent electrical insulating properties
  • Very low water absorption
  • FDA compliant


  • Susceptible to stress cracking
  • Lower stiffness than polypropylene
  • Poor UV resistance
  • Low heat resistance
  • High-frequency welding and joining impossible
  • Edges cannot be polished very highly
