Polypropylene

Finish Plastics | Corrosion Resistant Plastics

Polypropylene is an economical material that offers a unique combination of outstanding physical, chemical, mechanical, thermal, and electrical properties. It demonstrates excellent resistance to corrosion, organic solvents, degreasing agents, and electrolytic attack. It is also lightweight, stain-resistant and has a low moisture-absorption rate. Polypropylene is a tough heat-resistant material up to 180°F, making it ideal for the transfer of hot liquids or gases.

Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.

Grades and Colors

Polypropylene Homo-Polymer

Polypropylene homo-polymer is USDA/FDA, NSF and 3-A Dairy compliant in natural color for use in meat- and poultry-packaging facilities. This material demonstrates excellent impact resistance and formability, while also being lightweight. It also has outstanding chemical resistance and performs well in corrosive environments. Colors: Natural (translucent white), white, black and blue.

Polypropylene Co-Polymer

Polypropylene co-polymer offers the same chemical resistance of homo-polymer along with the added benefit of better resistance to stress cracking at low temperatures while being more reliable.

Flame-Retardant Polypropylene

Polypropylene also is available in two flame-retardant formulations. Both offer the best overall fire-resistant qualities of any compe titive FRP material. This flame resistance, however, does not come at the expense of aesthetics and high performance.
