    Styrene Butadiene Latex (SBR Emulsion) CAS 9003-55-8

    Styrene Butadiene Emulsion CAS 9003-55-8 is a stable aqueous dispersion of carboxylated styrene-butadiene copolymer , functioning primarily as a universal binder in paper coating, carpet backing, and construction materials. Commonly known as SBR Latex, this milky white liquid is engineered to provide superior adhesion, water resistance, and flexibility to various substrates. It is extensively utilized to enhance the printability of coated paper, bind fibers in tufted carpets, and serves as a critical modifier in cementitious mixtures (waterproofing and repair mortars) to improve bond strength and crack resistance. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications (varying Styrene/Butadiene ratios and solid content typically 50%) for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

    Product Description

    Styrene Butadiene (CAS 9003-55-8) is a milky white, anionic aqueous dispersion of a copolymer produced from styrene and butadiene. It is modified with carboxylic groups (Carboxylated SBR) to significantly enhance its mechanical stability, chemical stability, and adhesion properties compared to standard non-modified latex.

    Our SBR Latex series offers excellent binding strength, high compatibility with fillers (such as calcium carbonate and clay), and superior film-forming characteristics. It is engineered to provide the optimal balance between stiffness and flexibility, making it the preferred binder in the paper coating and textile industries.

    Applications

    SBR Emulsion is a versatile binder used across multiple industries:

    1. Paper & Paperboard Industry:

    • Coating Binder: Used as the primary binder in paper coating formulations. It enhances the surface gloss, smoothness, and ink receptivity of coated paper, ensuring sharp printing results.

    2. Textiles & Carpets (Major Application):

    • Carpet Backing: Acts as the adhesive to lock tufts into the primary backing and bond the secondary backing (jute or synthetic). It provides excellent pile anchorage and dimensional stability.
    • Non-Wovens: Used for impregnation and coating of needle-punched fabrics to provide stiffness and durability.

    3. Construction & Adhesives:

    • Cement Modification: When added to cement mortars, SBR latex improves bond strength, water resistance, and flexural strength. It is widely used in waterproof slurry and tile adhesives.
    • Road Surfacing: Used in asphalt modification to improve elasticity and prevent cracking (Specific Cationic grades available upon request).

    4. Lithium-Ion Batteries:

    • Anode Binder: Specially purified grades are used as a binder for graphite anodes in Li-ion batteries due to their electrochemical stability.

    Quality Assurance (QA/QC)

    At Industrochem, we recognize that latex stability is critical for your production process. Our manufacturing follows ISO 9001:2015 and ISO 14001 standards.

    • Particle Size Control: We use Malvern Laser Particle Size Analyzers to monitor the average particle diameter. A uniform particle size ensures consistent viscosity and binding power.
    • Residual Monomer Testing: Utilizing Headspace Gas Chromatography (HS-GC), we strictly control residual styrene levels to prevent odor issues in finished consumer goods (carpets/paper).
    • Mechanical Stability: Every batch undergoes rigorous high-speed agitation testing to ensure the emulsion does not demulsify or form coagulum during transport or high-shear mixing in your factory.

    Storage, Handling & Safety

    Storage Conditions:

    • Temperature Sensitivity:CRITICAL. SBR Latex is water-based. Store between 5°C and 35°C.
      • Do Not Freeze: Freezing will cause irreversible coagulation (breaking the emulsion).
      • Avoid Overheating: Prolonged exposure to high heat can cause surface skinning.
    • Containers: Keep containers tightly closed to prevent evaporation and crust formation.
    • Shelf Life: 6 months from the date of manufacture under proper storage conditions.

    Safety Precautions (HSE):

    • Toxicity: SBR Emulsion is non-toxic and non-flammable.
    • PPE Recommendations:
      • Skin: Wear rubber gloves and protective clothing to avoid prolonged skin contact, which may cause mild irritation due to the alkaline pH.
      • Eyes: Wear safety goggles. In case of contact, rinse immediately with plenty of water.
      • Ventilation: Ensure good ventilation in the processing area.

    FAQ - Technical & Supply Chain

    • Q:

      What is the functional difference between "Carboxylated" SBR Latex and standard SBR Latex?

      A: Carboxylated SBR (XSBR) contains carboxylic acid groups grafted onto the polymer backbone. This chemical modification significantly enhances the mechanical stability of the latex (reducing coagulation during high-speed shear) and improves adhesion to polar substrates like fillers, fibers, and cement aggregates, making it the preferred grade for paper coating and construction applications compared to non-carboxylated types.
    • Q:

      Does this emulsion tolerate freezing temperatures during storage?

      A: No. SBR Latex is a water-based dispersion and is sensitive to freezing. If the temperature drops below 0°C, the emulsion can irreversibly coagulate or "break," rendering it useless. Industrial storage and transport must be maintained between 5°C and 40°C to ensure stability.
