MP large creep deformation
Fenómeno do problema
MP product creep >5% under long-term load, exceeding the 2% requirement
Análise das causas
MP elastomer inherently large creep; molecular weight low, poor creep resistance; not crosslinked, large plastic flow
Solução
1) select a high molecular weight grade; 2) slight crosslinking 0.3wt% DCP to reduce plastic flow; 3) add rigid filler to reduce creep
Conclusão principal
large creep is caused by the elastomer nature; slight crosslinking and rigid filler are key
