Pengaruh platicizer DOP dan filler fiber glass terhadap kekerasan dan ketahanan pukul kompon acuan sepatu dari PVC

The aim of this research is to find out the effluence of DOP plasticizer and fiber glass as filler against hardness and impact resistance of shoe lasting compound made of PVC. PVC resin used as raw material, DOP as plasticizer and fiber glass as filler. Added to the resin beside plasticizer and filler, stabilizer and lubricant are also added. Variation of DOP used : 20, 25, 30, 35, 40, and, 45 part by weight fiber glass : 10, 15, 20, 25, and 30 part. Research results proves that the highest hardness value is 67 shore F achive by 20 part DOP, and 10 part fiber glass. The highest impact resistance (46,12 kg cm/cm) is compound using 40 part DOP and 10 part fiber glass. The influence of plasticizer DOP and filler fiber glass to the shoe lasting compund can be estimad by statistical regression and correlation , aproach there is Correlation between hardnes (Y1) and impact resistance (Y2) with variable of plasticizer DOP (X1) and filler fiber glass (X2) and Regression equation result as follow
