Abstract
The effect of cure characteristics and hardness of LCr filled SMR L compound were investigated. The size of LCr were 20 25 mm in range. Six compounds; 0, 5, 15, 25, 35 and 50 per hundred rubber (phr) of LCr were prepared by using two roll mill at room temperature. Cure characteristics such as scorch time,t2, cure time,t90, minimum torque, ML, maximum torque, MH, and cure rate index (CRI), and hardness of LCr filled SMR L were examined using rheometer. Result indicated that, all results for t2, t90, ML and MH shows the decrease with increasing in filler loading. CRI shows the increasing value with increasing LCr loading. Hardness, Ha value increase slightly with increasing LCr loading.
