Polyphenylene oxide (PPO) is one of the world's five general-purpose engineering plastics. Its chemical name is poly2, 6-dimethyl-1, 4-phenyl ether, which is made by the oxidation and condensation of 2, 6-dimethylphenol. It usually appears as a yellowish-brown powder or white granules and is mainly used in the fields of electronics and electrical appliances, automobiles, mechanical manufacturing, and medical care. This material is renowned for its high rigidity and heat resistance. Its long-term service temperature range is from -127℃ to 121℃, and its load deformation temperature can reach over 190℃.

Quantity:

It features low water absorption (0.06%), excellent electrical insulation (with the highest dielectric performance among engineering plastics) and corrosion resistance. The modified variety MPPO enhances processing performance by blending materials such as HIPS while maintaining heat resistance (glass transition temperature 211℃) and flame retardancy. The products are widely used in connectors, instrument panels, gears and other components. The molding process requires a temperature control of 280-330℃ and pre-drying treatment.


Advantages:

1.Outstanding physical properties: PPO can maintain its shape and size under mechanical stress and thermal exposure conditions, making it an ideal choice for precision parts. It is not prone to deformation under load or temperature changes, ensuring stable performance in industries such as automotive and aerospace.

2.Perfect electrical performance: PPO has excellent electrical insulation performance, and thus is suitable for electrical connectors and electronic components. It can withstand high voltage and has low dielectric loss, ensuring reliable and efficient performance in electrical applications.

3.Excellent chemical properties: PPO is resistant to acids, alkalis and detergents, ensuring long-lasting durability in harsh chemical environments.


Application:

1. Electronic and electrical fields

Electrical insulating materials: used in the manufacture of television tuning sheets, coil cores, microwave insulators and high-frequency printed circuit boards, etc.

High-voltage electronic components: Applicable to various high-voltage electronic components, such as relays, switches and cable housings, etc.

Household appliances: Widely used in the manufacturing of equipment such as televisions, copiers, and computer casings.

2. The automotive industry
