Polyphenylene oxide (PPO) is a high-performance amorphous thermoplastic known for its excellent thermal resistance, low moisture absorption, and dimensional stability. It is often used in blends, especially with polystyrene (e.g., Noryl®), offering balanced thermal, mechanical, and electrical properties.Polyphenylene oxide (PPO) is a high-performance amorphous thermoplastic known for its excellent thermal resistance, low moisture absorption, and dimensional stability.

• Electronics and electrical: Enclosures, connectors, PCB carriers, transformers, and insulators.
• Automotive: Ventilation components, lighting housings, under
• hood parts requiring dimensional and thermal stability.
• Home appliances: Internal dryer, washer, heater, and coffee machine components.
• Industrial: Enclosures, covers, and parts exposed to chemical and thermal stress.
• Excellent thermal stability: Retains mechanical properties up to 120–130 °C, ideal for thermally demanding applications.
• Low moisture absorption: Ensures stable dimensions and electrical performance in humid environments.
• Good electrical properties: High dielectric strength makes it suitable for electrical insulators and components.
• Chemical resistance: Withstands bases, salts, and detergents in industrial settings.
• Dimensional precision: Low thermal expansion enables precise molding.
• Poor UV resistance: Not naturally UV
• stable and degrades outdoors without additives.
• Moderate impact resistance: Less impact
• resistant than PC or ABS.
• Sensitive to some solvents: Not resistant to aromatic or chlorinated solvents.
