聚ju合he物wu填tian料liao使shi用yong兩liang種zhong黑hei滑hua石shi，一yi種zhong為wei煆duan燒shao滑hua石shi粉fen。因yin高gao溫wen燒shao製zhi而er成cheng，失shi去qu結jie晶jing水shui，層ceng狀zhuang晶jing體ti結jie構gou變bian為wei鏈lian狀zhuang結jie構gou
，硬ying度du增zeng大da
，能neng夠gou使shi用yong在zai需xu要yao提ti高gao硬ying度du和he強qiang度du的de塑su料liao製zhi品pin。另ling一yi種zhong為wei黑hei滑hua石shi料liao粉fen，在zai製zhi造zao黑hei色se塑su料liao中zhong可ke直zhi接jie使shi用yong。據ju研yan究jiu結jie果guo表biao明ming，在zai製zhi造zaoHDPE中增加黑滑石粉（其炭黑總量不超越3%）可加強衝擊強度
，增加黑滑石粉（其炭黑總量不超越5%）可增強拉伸強度。
