Polypropylene (PP)
Lightweight, chemically resistant thermoplastic for tanks and fabrication
Polypropylene is a lightweight, chemically resistant thermoplastic with good fatigue resistance and low moisture absorption — well suited to chemical tanks, pump components, and general fabrication. MK Industrial & Co.® supplies PP Homopolymer (PPHP) and PP Copolymer (PPCP) sheets and rods in Bangalore and Karnataka.
About Polypropylene
Polypropylene (PP) is a lightweight, chemically resistant thermoplastic with low moisture absorption and good fatigue resistance — able to flex repeatedly (as in a living hinge) without cracking. It resists a wide range of acids and alkalis, making it a cost-effective choice for chemical-handling equipment and general fabrication.
MK Industrial & Co.® stocks both PP Homopolymer (PPHP) and PP Copolymer (PPCP) grades in sheets and rods — available in standard dimensions and custom cut-to-size across Bangalore and Karnataka. For a detailed comparison between the two grades, see our PPHP vs PPCP page.
PP is widely used in chemical pump impellers, pickling tanks, and the packaging industry, wherever a lightweight, chemically resistant, easily fabricated plastic is needed.
