PP (Polypropylene)

PP, polypropylene, is a rigid and crystalline thermoplastic and is one of the top three widely used polymers in the industry. It has properties like durability, good dielectric strength, excellent electrical resistance, high toughness, and low friction. It also has good resistance to chemicals, stains, heat, and fatigue.

  • High Tensile Strength
  • Elasticity & Toughness
  • Fatigue Resistance
  • Good Water Resistance
  • High Melting Point
  • Biological Resistance
  • High Resistance to Electricity
