EVA toughness is insufficient with brittle fracture
Sorun Belirtisi
EVA product elongation at break <50%, brittle fracture without yielding
Neden Analizi
EVA molecular weight too low with insufficient toughness foundation; excessive crosslinking losing toughness; coarse crystallization increasing brittleness
Çözüm
1) Select high molecular weight EVA to improve toughness; 2) Control crosslinking degree to avoid excess; 3) Nucleating agent to refine crystallization and improve toughness
Temel Çıkarım
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is key
