PTFE (Polyetrafluorethylene)

Polypropylene (PP)Get A Quote

Polypropylene (PP) is a thermoplastic polymer, which can be used as a plastic, as well as a fiber. The plastic is used to construct various household, commercial, and industrial applications. This non-toxic plastic exhibits outstanding chemical, physical, mechanical, and thermal properties, which are not found in any other thermoplastic.

Beneficial Features and Chemical Properties of Polypropylene

PP is one of the most popular types of thermoplastic due to the following reasons:

  • High Operational Temperature and Melting Point: The plastic has a melting point of 320 degrees F, which is why it is used in applications, where temperatures may rise as a result of processing.
  • Easy to Customize: PP is an elastomer, which means it can be easily customized and fabricated to any desired shape. Manufacturers add additives to improve its physical and chemical properties.
  • Excellent Resistance against Variety of Elements: The plastic is highly resistant to organic solvents, water, and acid, alkalis, and electrolytic attacks.
  • Durable: The plastic is durable, does not absorb water, and can withstand daily stress.
  • High Compressive and Tensile Strength: PP has high compressive and tensile strength, which means it can resist stress and cracking.
  • Recyclable: PP is non-staining, non-toxic, and fully recyclable.
