Low EMA flexural modulus

문제 현상

EMA product flexural modulus <20% of design value

원인 분석

EMA soft with low modulus; filler addition insufficient or poor interface without reinforcing effect; crystallinity too low

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

EMA flexural modulus rigid filler nucleating agent crystallinity
