Polypropylene (PP)

  • PP, a polyolefin, is a thermoplastic made by the polymerization of propylene gas, a by-product of petroleum refining. 
  • With a good strength-to-weight ratio, PP offers a balance of thermal, chemical and electrical properties with moderate strength. It is ideally suited to environments where there is a concern for bacteria build-up that can interfere with the flow.
  • Approved for direct food contact.
  • Good insulating properties.
  • With excellent arc resistance and dielectric strength, PP can be used extensively in electrical applications.
  • PP has good resistance to chemicals and solvents, including aqueous, salts, acids, or alkaline solutions. It also has very low permeability to water vapor and gasses. 
  • When designing with PP, the coefficient of thermal expansion, modulus of elasticity, and compressive strengths need to be considered.
  • PP can be fabricated with standard woodworking tools. It can be butt welded, extrusion welded, fusion welded, and spun welded.
