PPS '2079851475616104452 insufficient crystallization poor performance
ظاهرة المشكلة
The mechanical and heat resistance properties of PPS products are not as expected.
تحليل الأسباب
PPS requires a high-temperature mold of 130-150°C to ensure full crystallization; when mold temperature <100°C, crystallization is incomplete, and HDT and strength decrease significantly.
الحل
Use oil temperature machine or electric heating mold, maintain mold temperature 140-150°C; ensure sufficient holding pressure and cooling time.
الخلاصة الأساسية
The excellent performance of PPS highly depends on sufficient crystallization.
