POM weather resistance shortcoming
Sorun Belirtisi
Outdoor POM parts chalk and embrittle on the surface after two years, especially in UV-irradiated areas
Neden Analizi
POM's weather resistance is not ideal, and ultraviolet rays cause surface degradation and chalking; natural-color material without a stabilization system has a short outdoor life, so outdoor applications must add stabilizers or select weather-resistant grades
Çözüm
①Select weather-resistant grades containing UV absorbers for outdoor parts; ②black carbon black filled parts have significantly improved weather resistance; ③evaluate material substitution for long-term sun exposure scenarios; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Weather resistance is POM's recognized shortcoming; outdoor applications are solved from the grade side, adding stabilizers is the bottom line and changing materials is the high line; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
