MP hardness too high
ظاهرة المشكلة
MP product Shore hardness 5-10 degrees higher than the target, hard to the touch
تحليل الأسباب
MP crystallinity high, rigidity increased; filler added too much; cooling too fast, crystallization incomplete but rigidity frozen
الحل
1) reduce cooling rate to complete crystallization and reduce the hard feel; 2) reduce filler addition; 3) add plasticizer 0.5wt% to lower hardness
الخلاصة الأساسية
high hardness is caused by crystallization and filler; adjusting cooling and filler are key
