Polypropylene is an economical material that offers a combination of
outstanding physical, chemical, mechanical, thermal and electrical
properties not found in any other thermoplastic. Compared to low or high
density polyethylene, it has a lower impact strength, but superior working
temperature range and higher tensile strength.
Polypropylene possesses excellent resistance to organic solvents,
degreasing agents and electrolytic attack. It is light in weight, resistant to staining,
and has a low moisture absorption rate. This is a tough, heat-resistant,
semi-rigid material, ideal for the transfer of hot liquids or gases. It is
recommended for vacuum systems and where higher heats and pressures are
encountered. It has excellent resistance to acids and alkalies, but poor
aromatic, aliphatic and chlorinated solvent resistance.
Features:
Lightweight, High tensile strength, Impact resistant, High compressive
strength, Excellent dielectric properties, Resists most alkalis and acids,
Resists stress cracking, Retains stiffness and flex, Low moisture
absorption, Non-toxic, Non-staining, Easily fabricated, High heat
resistance.
Fabrication:
Polypropylene can be easily fabricated using the following techniques:
Hot air welded, spin welded, fusion and butt welded, machined with wood
or metal working tools, vacuum formed, ultra-sonic welded.
Applications:
Chemical resistant tanks and linings, laboratory consoles, sinks and ducts, plating barrels
and tanks, die cutting pads, clean room walls, floors
and ceilings.
