Large EMA creep deformation
Fenómeno del problema
EMA product creep >5% under long-term load, exceeding the 2% requirement
Análisis de la causa
EMA elastomer nature with large creep; molecular weight too low with poor creep resistance; no crosslinking with large plastic flow
Solución
1) Select high molecular weight grade; 2) Slight crosslinking with 0.3wt% DCP to reduce plastic flow; 3) Add rigid filler to reduce creep
Conclusión clave
Large creep is caused by elastomer nature; slight crosslinking and rigid filler are key
