Penentuan Viskositas Remah Karet (Crumb Rubber) SIR 20 dengan Metode Mooney Viskometer di PT Pantja Surya

Abstract

Determination of crumb rubber SIR 20 has been with method Mooney viscometer at PT Pantja Surya by rotating of rator at a speed 2 rpm to connected micrometer scale 0 – 100 for show rasults viscosity. Value viscosity crumb rubber obtained range 75 M -80 M ,the value same of quality standard ISO 1903: 2011.
