PPO

Main Business Operations

Adhering to the research and development philosophy of "independent innovation," we are committed to achieving and ensuring every detail in the research, design, and production of powder processing for various industries, while maintaining the precision of the formulated solutions.

Concept Introduction 

Polyphenylene Oxide, commonly known as PPO, is one of the world's five major general-purpose engineering plastics. It boasts high rigidity, excellent heat resistance, flame retardancy, high strength, and superior electrical properties. Additionally, PPO is wear-resistant, non-toxic, and resistant to contamination. Its dielectric constant and dielectric loss are among the lowest in engineering plastics, virtually unaffected by temperature and humidity, making it suitable for low, medium, and high-frequency electric field applications.

Primary Use 

1. Suitable for manufacturing heat-resistant components, insulating parts, wear-resistant components, transmission parts, and medical and electronic parts.

2. Gear, fan blades, valves, and other parts suitable for use at higher temperatures, which can be used as a substitute for stainless steel.

3. Capable of manufacturing screws, fasteners, and connectors.

4. Electrical components for motors, rotors, casings, and transformers.

5. PPO and MPPO are primarily used in electronic appliances, automobiles, household electrical appliances, office equipment, and industrial machinery, utilizingPPO Plastic PowderHeat resistance, impact resistance, dimensional stability, scratch resistance, and peel resistance.

6. Paintability and electrical properties, suitable for automotive dashboard, radiator grates, speaker grilles, console, fuse box, relay box, connectors, and wheel arches.

7. Widely used in the electronics and electrical industry for manufacturing connectors, coil winding mandrels, mechanical component guards, switch relays, tuning equipment, large electronic displays, variable capacitors, battery accessories, microphones, and other components.

8. Components for home appliances such as televisions, cameras, videotapes, recorders, air conditioners, heaters, rice cookers, etc. Also serves as exterior parts and components for copiers, computer systems, printers, fax machines, and more.

9. Additionally, we offer casings and components for cameras, timers, pumps, blowers, noiseless gears, pipes, valves, surgical instruments, sterilizers, and other medical equipment parts.

10 Large Blow Molding Capabilities for Automotive Large Parts, such as air deflectors, bumpers, low foam molding ideal for high rigidity, dimensional stability, excellent sound absorption, and complex internal structures, suitable for various machine casings, bases, internal supports, with high design flexibility, and lightweight products.

Cautionary Notes 

Unmodified polyphenylene oxide (PPO) resins offer excellent mechanical, electrical, thermal, flame-retardant, and chemical stability properties, but they have poor solvent resistance, are prone to stress cracking in products, and have low notch impact strength. Additionally, they possess a critical weakness—high melt viscosity, which results in poor processability. Pure PPO resins cannot be molded by injection methods, significantly limiting their applications.

To overcome these drawbacks or impart new properties, various modifications have been made to PPO. These include chemical modifications (such as copolymerization, block, grafting, and crosslinking) and physical modifications (like blending, filling, reinforcement, and microcellular foaming).
