Polyphenylene Sulfide (PPS) offers the broadest resistance to chemicals of any high performance engineering plastic. According to its product literature, it has no known solvents below 392°F (200°C) and is inert to steam, strong bases, fuels and acids. However, there are some organic solvents which will force it to soften and craze. Minimal moisture absorption and a very low coefficient of linear thermal expansion, combined with stress-relieving manufacturing, make PPS ideally suited for precise tolerance machined components.
