The application of polyphenylene ether (PPO) in automotive parts is mainly reflected in its excellent performance, such as heat resistance, flame retardancy, dimensional stability and mechanical properties, etc. PPO plastic has excellent mechanical strength, stress relaxation resistance, creep resistance, heat resistance, water resistance, water vapor resistance and dimensional stability. Its non-toxicity and low relative density also provide advantages such as wear resistance, non-toxicity and pollution resistance.
Specific applications of PPO in automotive parts
The applications of PPO in automotive parts are very wide, mainly including the following aspects:
Electrical and electronic parts: PPO has good electrical insulation and water resistance, and is suitable for making a variety of electrical parts and electronic parts.
Industrial parts: Due to its excellent mechanical properties and thermal stability, PPO is also commonly used in the production of industrial parts1.
Automotive parts: PPO is particularly used in automotive parts, commonly used in the production of Gears, air blades, valves and other parts, and can even be used instead of stainless steel.
Processing characteristics of PPO
In the process, PPO injection molding is appropriate to take high-pressure, high-speed injection, holding pressure and cooling time can not be too long. The main flow channel of the mold is suitable for a larger taper or the use of pulling hooks, sprue to short and thick is good.
Comparison of PPO with other materials
Compared with traditional metal materials, PPO has lighter weight and lower cost, as well as excellent heat resistance and flame retardancy.
