EEA Insufficient Tensile Strength
Fenómeno do problema
EEA product tensile strength is 15-20% below the standard value
Análise das causas
EEA molecular weight low, strength foundation insufficient; filler interface poor, no reinforcing effect; excessive orientation, strong longitudinally and weak transversely
Solução
1) Select high-molecular-weight EEA grades; 2) Treat filler with coupling agent to improve the interface; 3) Reduce orientation to reduce longitudinal-transverse differences
Conclusão principal
Insufficient tensile strength is caused by molecular weight and poor interface; selecting high MW grades is key
