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