POE compression set large
Fenómeno do problema
POE product compression set >30%, below 15% requirement
Análise das causas
POE elastic recovery insufficient; crosslinking degree low, plastic deformation unrecoverable; density low, cell walls thin, recovery poor
Solução
1) Increase crosslinking degree to 60-70% to reduce plastic deformation; 2) Select high elastic recovery POE grade; 3) Add reinforcing filler
Conclusão principal
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
