King KPC Polypropylene is produced with our proprietary K-Stran™ process for unsurpassed flatness and quality up to 1” in thickness. For gauges up to 4”, our state-of-the-art compression molding system is utilized to create the same quality slabs.  We also have a proprietary process that makes massive shapes.

King KPC Polypropylene offers excellent resistance to chemicals, organic solvents, degreasing agents, and electrolytic products. It also has outstanding stain resistance with low moisture absorption. King KPC Polypropylene has exceptional impact resistance at room temperature, with good physical properties, low specific gravity, and is stiffer than King KPC LDPE or King KPC HDPE. King KPC Polypropylene offers a good balance of thermal, chemical and electrical properties with moderate strength. It possesses a good strength to weight ratio.

King KPC Polypropylene has good insulating properties. Its excellent arc resistance and dielectric strength allows polypropylene to be used extensively in electrical applications.

King KPC Polypropylene uses FDA approved materials, and is tested and certified by NSF; this means it is a good material candidate for professional food services, containment and operations. Other uses for KPC Polypropylene are larger span applications, filter presses and die-cutting surfaces.
