When Other Alloys Quit — The High-Performance Hybrid for Extreme Environments
Material Overview
PPO/PPS sits at the upper edge of the engineering plastic alloy spectrum — a compound formulated for the moments when standard high-performance polymers reach their limits. By blending modified PPO with polyphenylene sulfide, this alloy combines two of the most thermally stable amorphous and crystalline polymers commercially available.
The result is a material handling continuous use temperatures above 200°C, sustained chemical exposure to virtually any automotive or industrial fluid, and dynamic mechanical loading that would rapidly defeat lesser alloys. Renhong’s PPO/PPS compounds are specified for the most demanding industrial and EV applications, where decades-long reliability defines product value.
Key Features
🔥 Extreme Heat Resistance
Continuous use temperature exceeding 200°C; HDT above 240°C in glass-reinforced grades.
🧪 Strong Chemical Resistance
Resistant to virtually all automotive fluids, fuels, hydraulic oils, and most industrial chemicals.
⚙️ Wear Resistance
Specialty grades engineered for high-cycle dynamic applications such as rotors and gears.
⚡ Strong Electrical Properties
High dielectric strength and stable insulation under heat and humidity.
🔥 Inherent Flame Retardancy
PPS phase contributes to natural V-0 flammability without halogenated additives.
