SBR 1723 is a classic emulsion-polymerized styrene-butadiene rubber. It adopts low-temperature emulsion copolymerization technology, using butadiene and styrene as main monomers. With optimized formula and processing parameters based on traditional SBR 1712, this grade achieves improved self-adhesiveness, better bonding performance and superior processability. After strict procedures of polymerization, coagulation, dehydration and drying, the finished rubber presents uniform light brown texture with high plasticity and stable physical properties. It is specially formulated for manufacturing heavy-duty and high-strength rubber products with balanced wear resistance, tear resistance and processing stability.

Characteristics
This SBR 1723 grade delivers outstanding comprehensive performance with excellent processability and uniform filler dispersion, enabling smooth extrusion surfaces and stable curing speed with low scorch risk. The rubber compound is soft, easy to mix and features superior processing fluidity, perfectly applicable to continuous extrusion and calendering of thick rubber products. It maintains balanced mechanical properties with remarkable tensile strength, abrasion resistance, tear resistance and fatigue resistance, adapting well to heavy-load and high-frequency stress working conditions. Boasting moderate and excellent self-adhesiveness, it achieves tight bonding with cord fabric and steel wire core, effectively avoiding delamination and rubber shedding. Additionally, it has great thermal stability and stable heat generation control with reliable dynamic performance. It shows excellent compatibility with natural rubber and butadiene rubber, allowing flexible adjustment of product hardness and elasticity. Compared with ordinary styrene-butadiene rubber, this grade presents more stable overall performance and superior cost performance, coming in light beige bales with low impurity content.
