Recycled Natural Rubber Latex Gloves Filled CR Rubber: The Effects of Filler Size and loading

The effect of (rNR-G) as a filler with different size and loading on curing characteristics (scorch time, cure time, minimum and maximum torque) and physical properties (swelling test, crosslink density and hardness test) on rNR-G/CR (chloroprene) were investigated. Two sizes of fillers (fine size and coarse size) were utilized with different loadings (0, 5, 10, 15, 20 and 25 phr) for each size. The results indicated, the optimum cure characteristics for the (rNR-G)/CR compounds were at 5 phr for the fine size, meanwhile, for the physical properties, the hardness increased with the increasing of filler loading, and gave higher values in the case of fine size.
