Styrene-butadiene rubber 1723 is a high-viscosity oil-filled emulsion polymerized styrene-butadiene rubber. It has optimized the bonding and processing properties based on 1712, making it more suitable for heavy-duty and high-strength rubber products. It is mainly made from butadiene and styrene, filled with high aromatic oil and polymerized by emulsion. It appears as a light brown gel-like substance, has strong plasticity and good self-adhesiveness. It is often used in combination with natural rubber for heavy-duty tires, thick-walled conveyor belts, and large rubber components, balancing wear resistance, tear resistance, and processing stability.

FAQ
Q: What are the differences between 1723 and 1712?
A: 1723 has a higher oil content and stronger viscosity, suitable for heavy-duty tires and large conveyor belts; 1712 is mainly used for ordinary passenger car tires.
Q: Which products are mainly used for?
A: Tire sidewalls of heavy-duty tires, conveyor belts, large rubber rollers, engineering rubber accessories, etc.
Q: Storage precautions?
A: Store in a cool and dry place, avoid high temperature exposure and direct sunlight, and prevent the rubber blocks from becoming sticky and aging.
