PP Powder (Polypropylene)
PP powder is supplied in free-flowing form for rotational molding of chemical tanks, sintered filter media, and chemical-resistant metal coatings. It offers excellent chemical resistance, low density, and good fatigue resistance. Typical particle size ranges from roughly 100 to 500 µm depending on grade; specific particle size and grade are confirmed at time of quotation.
