All About : Polypropylene (PP) Thermoplastics

Polypropylene (also abbreviated to “PP”) is a by-product of petroleum refining. It is a polyolefin thermoplastic made by the polymerization of propylene gas. Through various techniques, we can modify its physical, chemical, and mechanical properties.

PP has many properties that make it a versatile material for manufacturing parts and components:

  • Good insulating properties
  • Good resistance to chemicals and solvents (including aqueous salts, acids, and alkaline solutions).
  • Low permeability to water, vapour, and gasses
  • Balances thermal, chemical, and electrical properties with moderate strength.
  • Good strength to weight ratio.
  • Has good arc resistance and dielectric strength (making it a good choice for electrical applications)
  • Easily fabricated using standard woodworking tools or extrusion
  • Can be butt welded, extrusion welded, fusion welded, or spun welded.

PP is a high-gloss surface, making it well suited for environments where bacteria buildup is common. It’s also approved for direct food contact, further expanding the possible uses of this versatile plastic.

PP is often the thermoplastic of choice for:

  • Tanks
  • Scrub stations
  • Piping systems
  • Semi-Conductor processing
  • Solar collectors
  • Water pumps
  • Cutting boards
  • Animal feeders
  • Radio and TV equipment
  • Packaging
  • Chemical process equipment
  • Laboratory equipment
