PPS is a crystalline plastic with high heat resistance (continuous use temperature of approximately 220°C) and superior mechanical strength, rigidity, flame resistance, chemical resistance, electrical properties and dimensional stability. The market for PPS has recently been expanding rapidly, taking advantage of its superior characteristics.
The primary uses of PPS is as electric/electronic components, automobile components, mechanical components (e.g., chemical pump), and components for semiconductor/liquid crystal manufacturing and testing equipment.
