TPE Automotive Application
Fenómeno del problema
TPE automotive seals have average weather resistance and fail at high temperature in the engine compartment
Análisis de la causa
TPE automotive seals are low cost and easy to assemble; but weather resistance and high-temperature resistance are average; engine compartment high-temperature scenarios require TPV; TPE has obvious advantages for interior parts; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Choose TPV for engine compartment high-temperature sealing; ②Choose TPE for interior and general sealing; ③Add stabilizer for weather resistance requirements; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
TPE automotive applications are zoned by temperature; the engine compartment gives way to TPV, and the interior is TPE's home ground; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
