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