CEF hardness too low
Fenómeno del problema
The Shore hardness of the CEF product is 5-10 degrees lower than the target and feels soft
Análisis de la causa
The soft nature of CEF has low hardness; too much plasticizer or softener is added; the crystallinity is low
Solución
1) Add rigid filler 5-10wt% to increase hardness; 2) Reduce the amount of plasticizer; 3) Increase the cooling rate to increase the crystallinity
Conclusión clave
Low hardness is caused by the softness of the material and excessive plasticization; adding fillers is the key
