SABO™ PPS (Polyphenylene Sulfide) Series

High heat resistance, chemical resistance, and high rigidity.

PPS (Polyphenylene Sulfide), also known as the "Plastic Gold," is a semi-crystalline, high-performance thermoplastic resin. It features high mechanical strength, high heat resistance (long-term service temperature of approximately 220°C), excellent chemical resistance, flame retardancy, good thermal stability, and outstanding electrical properties.

PPS-ST is based on PPS reinforced with high-performance glass fibers, significantly enhancing the rigidity and strength of the material, though its toughness is lower than that of neat PPS.

Key Features

Excellent dimensional stability due to low coefficient of linear thermal expansion and low water absorption

Continuous service temperature up to 220°C; note that the glass transition temperature is only 90°C, so caution is required for use under high load at elevated temperatures

Excellent fatigue and creep resistance

Stable dielectric constant and dissipation factor over a wide frequency range

Applications

Semiconductor

We provide high-purity, antistatic, and acid/alkali-resistant engineering plastics for precision components such as wafer carriers, packaging and testing equipment, and cleanroom accessories.

Aerospace

We specialize in lightweight, high-temperature-resistant, flame-retardant, and weather-resistant materials for applications such as cabin interiors, structural components, insulation parts, and precision aviation assemblies.

Automotive Manufacturing

We focus on lightweight, insulating, flame-retardant, and chemical-resistant materials for new energy vehicle battery, motor, and electronic control systems (three-electric systems), connectors, interior and exterior trim, and structural functional components.

Medical Devices

We utilize biocompatible, sterilizable, and hydrolysis-resistant medical-grade materials for diagnostic equipment, surgical instruments, and sterile structural components.

Energy Sector

We provide weather-resistant, insulating, corrosion-resistant, and high/low-temperature-resistant materials and structural components for photovoltaic, wind power, and energy storage applications.

Industrial Sector

We supply high-rigidity, wear-resistant, and self-lubricating materials for general components such as automation equipment, gears and bearings, pumps and valves, and fixtures and jigs.
