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.
Strengths
- Very low cost
- Excellent chemical resistance
- Very good processability
- Good low temperature resistance
- Excellent electrical insulating properties
- Very low water absorption
- FDA compliant
Limits
- 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
