EVA flexural modulus is low
문제 현상
EVA product flexural modulus is 20% below the design value
원인 분석
EVA is soft with low modulus; insufficient filler addition or poor interface not playing a reinforcing role; low crystallinity
해결 방법
1) Add 10-15wt% rigid filler to increase modulus; 2) Nucleating agent to increase crystallinity; 3) Select high modulus grade
핵심 요약
Low flexural modulus is caused by material softness and insufficient filler; adding rigid filler is key
