Effect of Shells Powder on Scorch and Cure Time of Elastomer Material

摘要

In the Present research the effect of shells powder additive (50,100,150 pphr) on scorch time ,cure time of natural rubber was studied .Oscillating Disk Rheometer was used to measuring the above times by specified the behavior of master batch through scorch time. The obtained results shown that the shells powder don’t have negative effect on rubber properties during vulcanization ,where the properties was enhanced after added this powder and the best percentage of addition was (100 pphr).
