CEF creep deformation large
Problem Phenomenon
The creep of the CEF product under long-term load is >5%, exceeding the 2% requirement
Cause Analysis
The elastomer nature of CEF has large creep; the molecular weight is low and the creep resistance is poor; uncrosslinked plastic flow is large
Solution
1) Select high-molecular-weight grades; 2) Slight crosslinking with 0.3wt% DCP to reduce plastic flow; 3) Add rigid fillers to reduce creep
Key Takeaway
Large creep is caused by the elastomer nature; slight crosslinking and rigid fillers are the key
