TECAFINE™polypropylene (PP) is homopolymer polypropylene plastic providing excellent chemical resistance to acids and bases. It is light weight and unaffected by moisture. This material is widely used in general purpose stamped parts and washer applications. It survives hot sulfuric acid in lead acid batteries in your car, acid resistant filter plates in the pulp and paper industry, and heat ages well enough to survive under the hood operating temperatures.
- 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.
