“…It was found that ENR/silica + VA compound showed the lowest Δ torque and the NR/BR compound on the other hand showed the highest Δ torque compared to the others. The Δ torque value considered as the parameter to demonstrate the degree of crosslink in rubber compounds [14][15] and low Δ torque of ENR/silica + VA may due to reduction of sulphur content in the formulation. The rheometer scorch time, t S2 , and Mooney scorch time, t 5 , of ENR/silica + VA also longer than other compounds which indicates of good processing safety [16] or less potential toward pre-mature vulcanization especially for extrusion and vulcanization process.…”

The challenges of using Epoxidised Natural Rubber (ENR) in truck tyre tread are to achieve good cure reversion resistant and physical properties especially on abrasion resistance towards long vulcanization time. The objectives of the project are to study the effects of vulcanization additive on cure characteristics and physical properties of silica filled ENR compound. In this work, a variation of curing systems were employed and a standard carbon black filled Natural Rubber/Butadiene Rubber (NR/BR) compound as a comparison. Greater reversion resistance and physical properties were observed with inclusion of vulcanization additive in the silica compound as compared to compound containing any. The abrasion resistance on the hand improved in spite of long vulcanisation time which commonly practices in truck tyre manufacturing.Keywords: ENR, silica, vulcanization additive, cure reversion, abrasion resistance
