Polyproplylene (Polypro)


Polypro – Polypropylene

PolyPropylene or PolyPro is extremely chemical resistant and light weight

Polypropylene combines high corrosion resistance, high-temperature resistance (Melting point is 320°F), and great tensile strength.

It maintains its stiffness at elevated temperatures and displays incredible resistance to organic solvents, degreasing agents, and electrolytic attack. In addition, the material is lightweight, and stain and moisture resistant.

Because of the incredible chemical resistance, Polypropylene can not be bonded or glued together. Polypropylene must be hot welded or the use of sonic welding to attach pieces together. This process, while outside of the norm, is quite common for the polyolefin family of plastics. Polypropylene is a durable industrial building material, and is made by some of the biggest names in Plastics, including Simona America, Rochling Plastics, Vycom Plastics, and Polymer Industries. These large manufacturers all run materials here in the USA and have some of the highest standards for production.

The other polyolefin material with the same welding requirements is Polyethylene.

Polypropylene is a High Tech Performance Plastic.

FRP-3 is a specialty type of fire resistant polypropylene.

Why you should use Polypropylene:

  • Self lubricating and low co-efficient of friction
  • High chemical resistance
  • Abrasion, Moisture, and Electrical Resistance
  • Stiffness, Rigidity, or cut resistance
  • Low specific gravity (floats in water)
  • Resistance to 180 degrees F and handles acids, alkalines and solvents extremely well
  • USDA and FDA approved for use in food processing applications
  • Excellent stiffness and rigidity
  • Very good dielectric properties
  • Impact and stress crack resistant
  • FDA and NSF compliant
  • Polypro is ITAR compliant, and Polypro is RoHS compliant

Polypropylene sheet is used in a broad variety of applications, but is particularly suited to the manufacture of chemical tanks for the following reasons:
  • Can be formed into almost any shape
  • Unsurpassed chemical resistance
  • Reliably handles all acids, alkalines and solver up to 180 degrees F
  • Resistant to abrasion, cuts and moisture
  • High tensile and compressive strength
  • Dependably maintains rigidity in all weather conditions
  • Superb dielectric properties
  • Wide variety of formulations including conductive, glass filled and static dissipative
  • approved by the USDA and FDA for use of food processing applications

Polypropylene Applications include:

Tanks, Scrubbers, Irrigation, Acid Waste Piping Systems, Battery Cases, Machine Cases, Etching equipment, Semi-conductor trays, Insulation components, Plating tanks, Living hinges, etc…
