  • It is a synthetic resin built up by the polymerization of propylene.
  • It is one of the important family of polyolefin resins.
  • Polypropylene is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required.
  • Properties of Polypropylene
    • It is highly resistant to chemical corrosion, making it an excellent choice for packaging of cleaning products and bleaches.
    • It is a commodity plastic with low density and high heat resistance.
    • Flammability: PP is a highly flammable material.
    • Density: PP is one of the lightest polymers among all commodity plastics.
  • Application of Polypropylene
    • It is widely used in polymer materials in the plastic manufacturing industry to produce various end products, especially plastic packaging.
    • Polypropylene has high insulation properties too, making it safe to use for plastic casing in electrical goods and cables. 
    • It offers impressive chemical and biological-resistant properties and makes polypropylene an obvious choice for the medical industry.
