Polyphenylene oxide (PPO) is a high-performance engineering plastic with excellent thermal stability, mechanical properties, electrical insulation properties and chemical corrosion resistance, which is widely used in the field of chemical production raw materials. This article will detail the nature and use of PPO.

1. The nature of PPO

1. Thermal stability
PPO has high thermal stability, can be used for a long time at high temperature, its thermal deformation temperature can reach above 170 ℃, and can maintain good mechanical properties and dimensional stability at high temperature.

2. Mechanical properties
PPO has excellent mechanical properties, its high strength, rigidity, impact resistance, good wear resistance and self-lubrication, can be used to manufacture high strength, high wear resistance of mechanical parts.

3. Electrical insulation performance
PPO has excellent electrical insulation performance, high volume resistance and dielectric strength, and can be used to manufacture electrical insulation parts and electronic components.

4. Chemical corrosion resistance
PPO has good chemical corrosion resistance, acid, alkali, salt and other chemical substances corrosion, can be used in the manufacture of chemical equipment and pipelines.

2. PPO use

1. chemical field
PPO in the chemical field has a wide range of applications, can be used in the manufacture of chemical equipment and pipelines, valves, pumps, etc., can also be used in the production of chemical containers and storage tanks. Because of its good chemical corrosion resistance and thermal stability, it can be used to transport and store various chemical substances.

2. Mechanical field
PPO has excellent mechanical properties and can be used to manufacture high-strength, high-wear mechanical parts, such as gears, bearings, seals, etc. At the same time, because of its good self-lubrication, it can also be used to manufacture parts of the lubrication system.

3.
PPO in the field of electrical appliances has excellent electrical insulation properties and can be used to manufacture electrical insulation parts and electronic components, such as wires and cables, capacitors, transformers, etc. At the same time, due to its good heat resistance and mechanical properties, it can also be used to manufacture housings and structural parts of electrical equipment.

4.
PPO in the automotive field also has a wide range of applications in the automotive field, and can be used to manufacture auto parts, such as bumpers, fenders, and engine hoods. Because of its good heat resistance, mechanical properties and dimensional stability, it can improve the service life and safety of auto parts.

In short, PPO, as a high-performance engineering plastic, has a wide range of applications in the field of chemical production raw materials. Because of its excellent thermal stability, mechanical properties, electrical insulation properties and chemical corrosion resistance, it can be widely used in chemical industry, machinery, electrical appliances, automobiles and other fields, which provides an important guarantee for improving the service life and safety of equipment.
