CEF compression set large
Problem Phenomenon
The compression set of the CEF product is >30%, lower than the 15% requirement
Cause Analysis
The elastic recovery of CEF is insufficient; the crosslinking degree is low and the plastic deformation is unrecoverable; the density is low, the cell wall is thin and the recovery is poor
Solution
1) Increase the crosslinking degree to 60-70% to reduce plastic deformation; 2) Select high elastic recovery CEF grades; 3) Add reinforcing fillers
Key Takeaway
Large compression set is caused by insufficient crosslinking; increasing the crosslinking degree is the key
