Styrene-butadiene rubber SBR-1502

Description

1. Product Overview

Styrene-butadiene rubber SBR-1502 is a premium, non-staining, cold-polymerized emulsion SBR with a light color and excellent processing stability, designed for high-performance industrial rubber goods. It is primarily used in tire manufacturing, mechanical rubber products, and footwear, offering superior abrasion resistance and tensile strength compared to natural rubber in dynamic applications. The key value proposition lies in its consistent Mooney viscosity and cure rate, enabling manufacturers to achieve predictable throughput and lower rejection rates. As the most widely specified general-purpose synthetic rubber globally, SBR-1502 is strategically critical for supply chain resilience and cost-efficient volume production.

2. Key Specifications & Technical Characteristics

• Chemical composition: Emulsion-polymerized styrene (23.5%) + butadiene (76.5%), non-staining antioxidant stabilized

• Purity: >99% rubber hydrocarbon; no oil extension

• Physical characteristics: White to light-cream bales; nominal Mooney viscosity ML(1+4) at 100°C: 50–55; specific gravity: 0.94

• Packaging options: 35 kg wrapped bales, 1.26 MT shrink-wrapped pallets, or 25 MT containerized blocks

• Shelf life: 12–24 months in original packaging under cool, dry, well-ventilated conditions (<30°C, <60% RH)

3. Core Industrial Applications

• Tire & automotive: Tire treads, sidewalls, conveyor belts, and vibration mounts – outperforms natural rubber in wet-skid resistance and heat aging.

• Industrial goods: Hoses, gaskets, roll covers, and shoe soles – delivers higher abrasion resistance and lower compression set than many general-purpose rubbers.

• Consumer durables: Floor tiles, matting, and battery boxes – cost advantage over alternatives due to faster mixing cycles and excellent filler acceptance.

• Cost advantage: Lower compound cost per unit volume than natural rubber or BR, with predictable cure behavior reducing energy and labor costs in molding operations.

4. Competitive Advantages

• Quality consistency: Batch-to-batch Mooney viscosity variation <±3 points, backed by ISO 9001:2025-certified production and SPC process control.

• Supply reliability: Multi-sourced from Tier-1 Asian and Middle Eastern producers with 98.5% on-time-in-full delivery track record.

• Logistics capability: Warehousing in Rotterdam, Houston, and Shanghai enabling 72-hour dispatch for urgent orders.

• Price competitiveness: Long-term supply contracts with 5–8% under regional index averages; no price volatility premiums.

• Sustainability: Option for ISCC Plus mass-balanced circular SBR-1502 with documented lower carbon footprint (up to 30% reduction).

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (BULK 20MT)

• Loading capacity: 25–27 MT per 20-foot dry container (standard bale stacking); 25 MT per 40-foot HC container when palletized
