Polypropylene Technical Data and Information

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.
