EEA Hardness Too Low
Problem Phenomenon
EEA product Shore hardness is 5-10 degrees lower than target, feels soft
Cause Analysis
EEA soft nature, low hardness; too much plasticizer or softener added; crystallinity low
Solution
1) Add 5-10wt% rigid filler to increase hardness; 2) Reduce plasticizer dosage; 3) Increase cooling rate to increase crystallinity
Key Takeaway
Low hardness is caused by material softness and excessive plasticization; adding filler is key
