PPO Automotive Underhood Parts
Sorun Belirtisi
[Problem Phenomenon] The underhood environment of high temperature and oil resistance is beyond the capability of ordinary plastics
Neden Analizi
PPO/PA alloy (GTX) is resistant to high temperature and oil, suitable for automotive underhood parts; PPX7110 is also recommended for automotive underhood applications; the semi-crystalline phase provides chemical resistance
Çözüm
Select GTX or PPX alloy for underhood parts; verify oil resistance and heat resistance according to working conditions; check creep for metal-replacement parts; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PPO alloy for underhood applications, GTX for oil resistance and PPX for stable dimensions; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
