EVA foam elastic recovery is poor
Fenómeno do problema
EVA foamed shoe sole compression recovery <70%, below 85%
Análise das causas
Crosslinking <60% with poor recovery; density too high with thick cell walls and rigid recovery
Solução
1) DCP 0.5-0.8wt% with crosslinking 60-70%; 2) Increase AC to reduce density to 0.25, reduce wall thickness and increase elasticity; 3) Reduce open cell content <10%
Conclusão principal
EVA foam elasticity is determined by crosslinking degree and density; moderate crosslinking and low density are key
