PP material, (chemically known as Polypropylene) is a semi crystalline thermoplastic. Polypropylene belongs to the group of polyolefins. Polypropylenes (PP) are universal standard plastics with well-balanced properties, providing excellent chemical resistance, high purity, low water absorption and good electrical insulation properties.
PP material offers:
- Excellent chemical resistance
- Very low moisture absorption
- High thermal expansion
- No stress crack formation
- Low toughness in minus temperature range making them sensitive to impact
