CMC Hardness Too High
ظاهرة المشكلة
Shore hardness of CMC products is 5-10 degrees higher than the target, feeling hard
تحليل الأسباب
CMC crystallinity is high and rigidity increases; too much filler added; cooling is too fast, crystallization is imperfect but rigidity is frozen in
الحل
1)Reduce cooling rate to perfect crystallization and reduce 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
