Chemical resistance is the ability of a material to withstand chemical attack. A material with low chemical resistance generally results in swelling or softening of the material, hence the material loses serviceability. Westlake Plastics offers a wide array of materials, from crystalline thermoplastics such as Polypropylene to fluoropolymers such as PVDF, which are used in many industrial process applications due to their high resistance to many chemicals.
Arolux Polyphenylene Sulfide (PPS) is a high performance semi-crystalline thermoplastic with continuous service temperatures up to 240°C, high hardness and rigidity, very good chemical and oxidation, very low water absorption, low creep (even at elevated temperatures) and inherent flame-retardant (UL 94: V-0). PPS is a popular choice for structural applications in demanding chemical environments at elevated temperatures.
