PP (Polypropylene) plastic fits among the lowest specific weight and highest chemical resistance thermoplastics available. It is impermeable to liquids and gases without reacting with the vast majority of industrial and pharmaceutical chemicals. It has minimal water absorption, providing good dimensional stability.
In addition to its chemical resistance, it has high impact resistance and good thermal and electrical stability. Its material is non-sticking and easy to machine, being weldable and moldable for the desired application. One of its unique features is the ability to make pieces with folds in the material itself.
Moldable and weldable
Optimal for applications requiring high chemical protection.
PP engineering plastic can be applied to industrial and laboratory cutting tables, fiber industry molds, chemical tanks and piping, orthopedic appliances, folding bottle caps, eyeglass cases, plastic chairs, flexible packaging, tupperware, auto parts, gears, silo liners, rotors, fittings and valves.
Polypropylene has low resistance to sudden climate change and can cause stains and property loss when exposed to the sun. To solve this problem, the polymer can be additived with antioxidant and ultraviolet stabilizer to delay wear.
