Product profile: Polyopropylene rod & Tube

Polyopropylene (PP) is a thermoplastic made by the polymerization of propylene gas, given off as a by-product of petroleum refining. The properties of this versatile plastic can vary through various techniques.

Features of polyopropylene rods and tubes

  • Hard, high gloss surface
  • Resists chemicals, solvents (including aqueous, salts, acids, and alkaline solutions)
  • Low permeability to water vapour and gases
  • Good balance of thermal, chemical, and electrical properties with moderate strength
  • Good strength to weight ratio
  • Good insulating properties
  • Can be fabricated with standard woodworking tools, butt welded, extrusion welded, fusion welded, or spun welded.

When designing projects for Polyopropylene rods and tubes, consider the coefficient of thermal expansion, modulus of elasticity and compressive strengths.

We most often see PP used in environments where there is concern of bacteria build-ups that interfere with flow. As such, it’s approved for direct food contact and is also ideal for electrical applications because of its excellent arc resistance and dielectric strength.

Applications for Polyopropylene rods and tubes

  • Tanks – Scrub stations
  • Piping systems
  • Semiconductor processing
  • Solar collectors
  • Water pumps
  • Cutting boards
  • Animal feeders
  • Radio and TV Equipment
  • Packaging
  • Chemical process equipment
  • Laboratory Equipment
