MP fast thermal aging

Fenómeno do problema

MP products after aging at 80°C for 7 days, mechanical properties decline >30%

Análise das causas

MP molecular chains break and degrade under thermal oxidation; antioxidant system incomplete, protection insufficient

Solução

1) improve the antioxidant system 1010+168+DSTDP; 2) select a high molecular weight grade; 3) add metal deactivator 0.05wt%

Conclusão principal

thermal aging is caused by thermal oxidation; improving the antioxidant system is key

MP thermal aging thermal oxidation antioxidant high molecular weight
