Abstract

Crumb rubber is rubber one be made specially, so its technical quality is secured and its establishment is gone upon on technical character. One of parameter which is analysed on crumb rubber which is dirt content. And sample that is analysed is crumb rubber which come from cuplump raw material (SIR 20), and crumb rubber which come from latex raw material (SIR 3), one that have default point corresponds to Standard Indonesian Rubber (SIR) which is maximum 0,20% for crumb rubber which come from cuplump raw material and a maximum 0,03% for crumb rubber which come from latex raw material. Influence from higher dirt content to high quality of crumb rubber very bad, since gets to reduce preeminent dynamics character from vulcanisation nature rubber. So the higher its dirt content therefore quality it will on the lower, and if getting dirt content little its therefore quality it will get nicely.
