Description
SBR is a synthetic rubber copolymerized from styrene and butadiene, known for its excellent abrasion resistance, aging resistance, and wet skid resistance. SBR is divided into emulsion styrene-butadiene rubber (ESBR) and solution styrene-butadiene rubber (SSBR).
Applications
Tire industry
Industrial products: Conveyor belts, hoses, seals, waterproof membranes
Other fields: Wire and cable sheathing

FAQ
Q: Do you sell finished products or raw materials?
A: We only supply rubber compounds, not finished products. You can choose hardness, color, and formulation based on your product needs. We mix to order and deliver.
Q: What rubber types can you handle?
A: Common types include NR, SBR, BR, NBR, EPDM, CR, silicone rubber, fluororubber, etc., subject to actual capability.
Q: Are hardness and formulation linked?
A: No. The same hardness can be achieved with different formulations. The difference lies in tensile strength, tear resistance, compression set, oil resistance, aging resistance, etc. Tell us your application and we’ll recommend the right system.
Q: Can you compound to the customer’s formula?
A: Yes. We support toll processing with customer-supplied materials or mixing to a customer-specified formula. We can also recommend a formula based on performance requirements.
Q: How do you ensure batch-to-batch consistency?
A: Through raw material batch control, fixed mixing process parameters, and sampling tests (hardness, specific gravity, Mooney viscosity, etc.).
