Details of Sbr Latex

SBR Latex (Styrene-Butadiene Rubber Latex) is a synthetic rubber emulsion that is widely used in various industries due to its excellent mechanical properties, flexibility, water resistance, and cost-effectiveness.

 

Here's a comprehensive overview:

 

🔬 Chemical Composition

Main components: Styrene and butadiene (typically in a 23:77 ratio)

 

Form: A milky-white liquid emulsion (water-based)

 

Chemical formula: (C₈H₈·C₄H₆)ₙ (copolymer of styrene and butadiene)

 

⚙️ Key Properties

Property Value / Description

Appearance Milky white liquid

pH 6.5–10.0 (varies with formulation)

Solid Content 45–55% typical

Viscosity 50–500 mPa·s

Particle Size ~100–300 nm

Glass Transition Temperature (Tg) ~ -50°C to -20°C

Film Forming Ability Excellent

Water Resistance Good to excellent

UV/Ozone Resistance Poor (needs additives for improvement)

 

🧪 Production Method

SBR latex is typically produced via emulsion polymerization, involving:

 

Monomers: Styrene and butadiene

 

Surfactants/Emulsifiers

 

Initiators: Organic peroxides or redox systems

 

Optional: Antioxidants, stabilizers

 

🏭 Applications

SBR latex is extremely versatile. Common uses include:

 

🏗 Construction

Cement and mortar modification (improves flexibility and water resistance)

 

Waterproof coatings

 

Bonding agents for tiles and repair mortars

 

🧤 Gloves & Textiles

Dipping for rubber gloves

 

Coating for non-woven fabrics

 

Carpet backing

 

📄 Paper Industry

Coating and sizing

 

Improves gloss, smoothness, and printability

 

🖌 Paints and Adhesives

Binder in latex paints

 

Adhesives for various substrates (especially pressure-sensitive types)

 

✅ Advantages

Cost-effective compared to natural latex or other synthetic rubbers

 

Excellent film-forming properties

 

Good mechanical strength and abrasion resistance

 

Emulsion form allows easy handling and application in water-based systems

 

⚠️ Limitations

Poor resistance to ozone, UV, and oxygen unless modified

 

Lower elasticity compared to natural rubber

 

Not suitable for high-heat or highly chemical-resistant applications without further formulation

 

📦 Storage & Handling

Store between 5°C and 30°C

 

Avoid freezing

 

Use stainless steel or plastic containers to avoid metal ion contamination
