EEA Large Creep Deformation
Fenómeno do problema
EEA product creep >5% under long-term load, exceeding the 2% requirement
Análise das causas
EEA elastomer nature has large creep; molecular weight low, creep resistance poor; not crosslinked, large plastic flow
Solução
1) Select high-molecular-weight grades; 2) Slightly crosslink with 0.3wt% DCP to reduce plastic flow; 3) Add rigid fillers to reduce creep
Conclusão principal
Large creep is caused by the elastomer nature; slight crosslinking and rigid fillers are key
