Polyphenylene Oxide (MPPO Modified PPO)

 Polyphenylene Oxide (PPO pellets) are small, uniform granules of Polyphenylene Oxide, a high-performance engineering plastic prized for exceptional heat resistance, dimensional stability, electrical insulation, and chemical resistance, often blended with other plastics like HIPS (Modified PPO or MPPO) to enhance processability and impact strength for automotive, electronics, and medical device parts, acting as a versatile, durable raw material.

Key Characteristics

- Heat Resistance: Heat distortion temperature approximately 120–170℃ (adjustable depending on PPO content), long-term operating temperature **-40℃~120℃**.

- Electrical Properties: Low dielectric constant and loss, wide temperature and frequency stability, excellent insulation.

- Mechanical Properties: High rigidity, creep resistance, fatigue resistance, and stress relaxation resistance.

- Environmental Protection: Halogen-free flame retardant, low smoke and low toxicity, compliant with EU and North American environmental requirements.

- Processing: Injection molding/extrusion friendly, customizable with fiber reinforcement, flame retardancy, antistatic properties, toughening, and other modification options. Application Scenarios

- Electronics & Electrical Appliances: Transformer frames, relay housings, connectors, coil frames, switch bases.

- Automotive: Dashboard frames, sensor housings, interior structural components, connectors.

- Precision Components: Water meter/pump parts, textile yarn tubes, gears, bearings, pump impellers. Typical Models & Customization

- General Purpose: High rigidity, easy to process, suitable for general structural components.

- Flame Retardant Grade: UL94 V0, used for flame-retardant electronic and electrical components.

- Glass Fiber Reinforced Grade: Improves strength and heat resistance, used for high-load components.
