PPS (Polyphenylene Sulfide) products are renowned for their exceptional chemical resistance among advanced engineering plastics. Resistant to solvents below 392°F (200°C) and impervious to steam, strong bases, fuels, and acids, they offer minimal moisture absorption and an extremely low coefficient of linear thermal expansion. These qualities, further enhanced by Quadrant's proprietary stress-relieving processes, ensure PPS products are highly suitable for precision-machined components with exacting tolerances. Additionally, PPS products exhibit outstanding electrical properties and inherent flame retardancy, making them ideal for a wide range of industrial applications.
