As a reliable SBR 1723 supplier, we provide ASTM-compliant industrial grade rubber bales with consistent batch quality and stable bulk supply, serving tire manufacturing, industrial rubber goods and footwear industries worldwide.
Eco-friendly formula with global compliance: SBR 1723 adopts TDAE low-PAHs extender oil, which complies with EU Directive 2005/69/EC and REACH regulations, making it suitable for export-oriented rubber products targeting European and North American markets without environmental trade barriers.
Excellent processability & high filler loading: The 37.5phr oil extension gives SBR 1723 stable Mooney viscosity and excellent plasticizing performance, adapting smoothly to mixing, calendering, extrusion and molding processes. It supports high carbon black and filler loading, effectively reducing formula cost and improving production efficiency.
Outstanding abrasion & dynamic fatigue resistance: SBR 1723 exhibits good wear resistance, tear strength and flex cracking resistance. It maintains stable load-bearing performance under long-term dynamic working conditions, with good reversion resistance during vulcanization and excellent low-temperature flexibility of finished products.
Broad blending compatibility: It can be blended in any proportion with natural rubber, polybutadiene rubber and other general-purpose elastomers, allowing flexible formula adjustment to balance performance, cost and environmental requirements for different end products.
Good thermal & weather aging resistance: Under normal service temperatures, SBR 1723 delivers better heat aging and weather cracking resistance than natural rubber, maintaining stable physical properties in outdoor and medium-temperature industrial scenarios.

FAQ
What are the main applications of SBR 1723?
SBR 1723 is primarily used in tire treads, sidewalls, camelback retreading compounds, rubber conveyor belts, shoe soles, hoses, molded rubber parts and other black industrial rubber products. It is especially preferred for export-oriented rubber goods requiring both balanced performance and EU environmental compliance.
What is the difference between SBR 1712 and SBR 1723?
The core difference lies in the type of extender oil and environmental compliance: SBR 1712 uses traditional high aromatic DAE oil, while SBR 1723 adopts low-PAHs TDAE eco oil that complies with EU 2005/69/EC and REACH regulations. Their bound styrene content, oil loading level and basic mechanical properties are highly similar, but SBR 1723 is more suitable for export products targeting European and American markets.
What is SBR 1723?
SBR 1723 is a cold emulsion-polymerized, oil-extended styrene butadiene rubber (E-SBR) filled with 37.5 phr TDAE eco-friendly extender oil, with 22.5–24.5% bound styrene and a staining antioxidant system. It is an environmentally compliant general-purpose synthetic rubber widely used in tire manufacturing and industrial rubber products for its excellent processability and abrasion resistance.
