TECAFINE™PP (polypropylene) is an anti-stated, poly-propylene, random copolymer polyolefin engineering plastic providing excellent chemical resistance and high purity. FDA compliant with better mechanical properties than other typical polyolefin materials, it is light weight, weldable, and unaffected by moisture. Ensinger?s unique processing technology provides unsurpassed quality in TECAFINE™PP stock shapes.

  • Excellent chemical resistance
    TECAFINE™PP is resistant to organic chemicals, solvents, mineral acids, and inorganic salts.
  • Weldable
  • High purity
    TECAFINE™PP nonparticulating and suitable for high purity environments.
  • Light weight
    TECAFINE™PP has a specific gravity of less than 1.
  • Moisture resistant
    TECAFINE™PP is unaffected by water or moist environments.
  • Unsurpassed quality
    Ensinger’s unequaled extrusion expertise means users consistently obtain the highest quality polypropylene stock shapes.

TECAFINE™PP?s excellent chemical resistance and high purity characteristics make it ideal for use in the food-processing and chemical-processing industries. Common applications include pump and valve components, tanks, laboratory equipment, and other parts in contact with corrosive environments.
