Chemical Resistance, High Strength and Dimensional Stability

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.

Uses

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.

Characteristics

PPS has superior dimension stability because of its extremely low water absorption and low linear expansion coefficient.
PPS is extremely resistant to chemicals, and can withstand not only organic acids such as acetic acid but also strong inorganic acids such as hydrochloric and sulfuric acid. It is also not affected by strong bases.
Although it has a high continuous use temperature of 220°C, it has a low glass transition temperature of 90°C; therefore care is required when PPS is used under high temperatures and high loads.
PPS has high strength and high rigidity, as well as superior resistance to fatigue and creep.
The grade recommended for superior sliding wear is PPS230AE3.
