Not directly. SBS is usually the main modifier in SBS membrane or PMB systems. SBR is more suitable as a supporting modifier to improve performance and help optimize formulation cost.

Can SBR be used in APP membrane?

Yes. SBR can be tested as a supporting modifier in APP membrane systems. APP has good heat resistance, but sometimes flexibility and peel adhesion may not be enough. Adding SBR may help improve flexibility, crack resistance, bonding performance, and peel adhesion.

Is SBR latex suitable for hot bitumen mixing?

Usually no. SBR latex contains water, so it is generally not suitable for high-temperature hot mixing. For hot bitumen systems, SBR powder or granules are usually more suitable.

What key parameters should buyers check for SBR Latex?

Important parameters include: Solid content Viscosity pH value Particle size Stability Application compatibility

Why is trial testing important?

Because every customer's formulation is different. The final performance depends on raw materials, dosage, mixing temperature, processing conditions, and target performance. Trial testing helps confirm compatibility and the best dosage.

AI-Powered supplier vetting

SummaryThe supplier operates across waterproofing materials, rubber-related products, mechanical equipment, textiles, chemicals, building materials, and selected medical supplies. It states that it provides OEM services for well-known brands and reports multiple technical patents and ISO9001 certification. Quality assurance and raw-material traceability are identified, but the available evidence also shows no SDK, no inventory, no overseas warehouse or showroom, no valid manufacturing-capacity contract with related subcontractors, and no documented corrective-action or complaint-handling procedures. Lead time is stated as within 15 working days in both peak and off-season, but supplier-service governance documentation is incomplete. Financial records are referenced for 2022–2024, without sufficient detail to assess credibility. R&D resources are limited in the evidence, with one engineer and no available design-control documentation.

CertificationsThe company states that it has passed ISO9001 quality management system certification and holds multiple technical patents. This is explicit evidence of certification and technical recognition, although no certificate number, validity period, or certification scope is provided.

After-Sales capabilityThe supplier states that it has no overseas warehouse or showroom, and it has no written procedures or records for corrective and preventive actions or effective customer-complaint handling. These documented gaps indicate weakly evidenced after-sales service infrastructure.

Production capacityThe supplier reports no valid manufacturing-capacity contract with its related subcontractors and no in-stock capacity. It states an average lead time within 15 working days in both peak and off-season, but service-capability governance lacks written assessment procedures and an approved-supplier list. Overall production capacity is not sufficiently substantiated and includes explicit control gaps.

Customization capabilityThe supplier explicitly states that it provides OEM services for well-known brands and offers products intended to meet varied customer demands. Quality assurance and raw-material traceability are also reported, but the absence of an SDK and formal R&D audit documentation limits evidence for technically complex customization.

Product Q&A

Q:What is SBR?

SBR stands for Styrene-Butadiene Rubber. It is a synthetic rubber / polymer material used to improve flexibility, adhesion, crack resistance, and durability.

Q:What are the main types of SBR?

SBR is commonly supplied as: SBR Latex SBR Powder SBR Granules SBR Rubber Bale, such as SBR 1502 and SBR 1712

Q:Is SBR water-soluble?

No. SBR powder, granules, and rubber bales are not water-soluble. SBR latex is a water-based dispersion, not truly water-soluble.

Q:Where is SBR Latex used?

SBR latex is mainly used in: Cement mortar Waterproof coating Tile adhesive Concrete repair Construction chemical systems

Q:Where are SBR powder and granules used?

SBR powder / granules can be used in: APP/SBS membrane systems Bitumen modification PMB systems Asphalt modification Rubber-related applications
