“…This image supported the highest tensile strength for 75 phr/25 phr of NR/vCR blends. A similar explanation has been reported where more tearing lines mean strong interfacial adhesion and effective wetting in rubber blends, responsible for better tensile strength [36]. Figures 10D-F show tensile fractured surfaces for NR/ rCR blends with 95 phr/5 phr, 75 phr/25 phr and 50 phr/50 phr, respectively; that is, similar blend ratios as shown for NR/vCR blends in Figures 10A-C.…”

“…For example, the value of M L was obtained at 0.95 dNm with an addition of 15 phr of rCR, while the value of M L for vCR at the same loading was recorded at 0.85 dNm. Noriman et al [36] explained that the difficulty of processing in SBR/rNBR blends was due to the presence of a crosslink in rNBR rubber and other additives. A similar explanation can be used in this study, because rCR was obtained as a vulcanized product.…”

“…As explained earlier, rCR is stiffer than vCR, which caused rCR to act at stress concentrations producing a heterogeneous nature in blends which was responsible for fatigue failure with a lower cyclic deformation. In addition, Noriman et al [36] explained that higher friction between rubbers blends in SBR/rNBR blends than in SBR/ vNBR blends consequently caused a greater reduction in fatigue life in SBR/rNBR blends.…”

“…For instance, investigation regarding the usage of recycled acrylonitrile butadiene rubber (rNBR), originally from rejected gloves, blended with virgin styrene butadiene rubber (SBR), has been reported with several variables [16][17][18][19]. In addition, there is also a work regarding recycled ethylene-propylene-diene monomer in the natural rubber (NR) blend [20].…”

The effects of various ratios of virgin chloroprene rubber (vCR) and recycled chloroprene rubber (rCR) with a constant content of carbon black (CB) on the properties of natural rubber/chloroprene rubber NR/CR blends were studied. The minimum torque (M L ), maximum torque (M H ), scorch time, and cure time increased with the addition of both CRs and the effects of rCR were more pronounced than vCR on these properties. The tensile strength and fatigue life of the NR/vCR blends increased with an addition of vCR up to 25 phr and then decreased with a higher vCR. However, NR/rCR blends reflected otherwise for both properties. The elongation at break and swelling percentage of NR/CR blends decreased with the addition of both vCR and rCR.

“…Both of TOR and ENR-50 helped to improve the distribution of the rNR-G filler within the CR. With the better distribution, the interaction between rubber-filler would improve [14,15]. Thus, the tensile strength improved with the incorporation of compatibilizers.…”

Abstract. In this study, the effects of the compatibilizers; trans-polyoctylene (TOR) and epoxidized natural rubber (ENR-50), on the cure characteristics and tensile properties of recycled natural rubber latex gloves (rNR-G) filled chloroprene rubber (CR) were investigated. Blends consisting of rNR-G in a weight ratio 20 phr in CR and The compatibilizers TOR and ENR-50 at different concentrations, i.e. 2, 4, 6, 8 and 10 phr, were prepared using a two roll mill. Incorporation of TOR resulted in a reducing of the cure characteristics, meanwhile ENR-50 increased them. On the other hand, both of TOR and ENR-50 were improved tensile properties. These effects are attributed to the enhanced interfacial adhesion between rNR-G and phases through the compatibilizing effect induced by TOR and ENR-50, and the good dispersion of the rNR-G phase in the CR matrix. The results confirmed that TOR and ENR-50 could potentially be used as compatibilizers for the recycled natural rubber latex gloves filled chloroprene rubber.

The dependence of peel strength and shear strength of epoxidized natural rubber (ENR-50)-based pressure sensitive adhesive on molecular weight and rate of testing was investigated using coumarone-indene as the tackifying resin. Toluene and polyethylene terephthalate were used as the solvent and substrate respectively, throughout the study. A SHEEN hand coater was used to coat the adhesive on the substrate at a coating thickness of 120 lm. All the adhesion properties were determined by a Llyod Adhesion Tester operating at different rates of testing. Result shows that peel strength and shear strength increases up to an optimum molecular weight of 4.2 Â 10 4 of ENR 50. For peel strength, the observation is attributed to the combined effects of wettability and mechanical strength of rubber at the optimum molecular weight, whereas for the shear strength, it is ascribed to the optimum cohesive and adhesive strength which enhances the shear resistance of the adhesive. Peel strength and shear strength also increases with increase in rate of testing, an observation which is associated to the viscoeslastic response of the adhesive. DSC and FTIR study confirms the miscibility of tackifier and the ENR 50.
