Friction and wear performance of high density polyethylene / styrene – butadiene rubber polymer blends [Rezistenţa la uzură şi fricţiune a amestecurilor compozite de polietilenă de înaltă densitate cu cauciuc stiren-butadienic]

Abstract

In the present work, the friction and wear property of high density polyethylene / Styrene - Butadiene Rubber polymer blends was studied. Styrene - Butadiene Rubber addition in the HDPE was 5, 10, 15, and 20 wt%. The result showed that the addition of fillers to the composite changed the friction coefficient and wear rate. All specimen wear loss increases with increasing load and sliding distance; meanwhile the friction (static and dynamic) coefficient increases. Wear rate of all HDPE composites are larger than that of pure HDPE. The results obtained in this study indicate that HDPE / Styrene - Butadiene Rubber polymer applied to the abrasion test indicate that road and load values to increase the effect of wear, but this effect by increasing the rate of Styrene - Butadiene Rubber additives lead to a reduction in wear is observed that value. In the friction test, the coefficients of friction are the rate of increase Styrene - Butadiene Rubber that the friction coefficient increases. © 2015, Procema SA. All rights reserved.
