Embrittlement of PBT products after adding conductive carbon black
ظاهرة المشكلة
When conductive carbon black is added to PBT to prepare antistatic/conductive products, the toughness decreases significantly.
تحليل الأسباب
The carbon black filling amount is high (>15%), restricting molecular chain movement; carbon black agglomerates form stress concentration points; no toughening agent is used.
الحل
Control the carbon black filling amount and use high-efficiency conductive carbon black; add elastomer toughening; use coupling agents to improve the interface.
الخلاصة الأساسية
PBT conductive modification needs to balance conductivity and toughness.
