Superior abrasion resistance prolongs product lifespan in applications subjected to intense friction and mechanical stress, making it a perfect solution for tire treads, industrial belts, footwear soles, and vibration mounts.

Enhanced processing efficiency is achieved through oil extension at 37.5 phr, ensuring reduced viscosity that supports easier mixing, improved filler dispersion (carbon black, silica), and uniform curing. This leads to lower energy use, shorter processing times, and reduced overall compounding costs.

Its excellent dynamic and tensile properties stem from balanced styrene content, contributing to superior hardness, tear strength, and resilience. The design minimizes heat buildup during repetitive stress scenarios in applications such as conveyor belts, shock absorbers, and automotive components.

With high compatibility to natural rubber (NR), the blend boosts tensile strength and elasticity, ideal for tire carcasses, shoe soles, and heavy-duty technical products. It also allows customized compound formulations tailored to meet specific mechanical and economic needs.

Outstanding aging and weather-resistant properties protect against ozone cracking, UV deterioration, and oxidative aging. This ensures enduring reliability in challenging outdoor or extreme industrial environments.

As a cost-effective solution, it delivers solid performance while lowering reliance on high-cost elastomers. It serves as an economical alternative to natural rubber for high-volume production, enhancing performance without inflating production expenses.

Packaging and Export

TJPC SBR 1712 is carefully packaged and exported in adherence to strict international standards, ensuring product stability, hygienic handling, and safe transportation across global supply chains. The packaging is specifically designed to protect the rubber from contamination, moisture, oxidation, and potential mechanical damage during loading, transit, and storage.

SBR 1712 is generally provided in 25 kg bales, enclosed in polyethylene film or anti stick liners to prevent adhesion. These bales are then stacked on either wooden or plastic pallets, with each pallet typically holding 1,000 to 1,200 kg, tailored to meet customer specifications. Pallets are tightly secured using stretch wraps or metal/plastic straps to maintain stability throughout transit.

 For high volume purchases, the material is also available in jumbo bags, typically weighing 1,000 kg each. These bags facilitate improved handling efficiency for industrial scale consumption. Constructed from multi layer woven polypropylene with inner moisture-resistant liners, jumbo bags are ideal for protecting the material in humid conditions.

The packaging is specifically designed to limit exposure to air and UV light. While SBR 1712 demonstrates strong stability, prolonged exposure may accelerate oxidation. Consequently, protective wrappings and pallet covers are employed, particularly for shipments routed through areas with high temperatures or humidity.

Export arrangements are customized based on the destination and client preferences. Most shipments are transported in 20-foot or 40-foot containers, determined by weight restrictions and order volumes. To protect the cargo from condensation or container sweat during extended sea voyages, containers may be lined with kraft paper or polyethylene sheets.

Although SBR 1712 does not require temperature-controlled conditions, avoiding prolonged exposure to extreme heat exceeding 40°C is advisable as it may soften the packaging and cause bale deformation. Storage facilities should be clean, well ventilated, dry, and away from direct sunlight or heat sources.

Export documentation includes essential items such as a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), packing list, commercial invoice, and certificate of origin. Some markets necessitate compliance with specific environmental or chemical regulations for instance, REACH requirements in Europe or EPA related documents for shipments to the United States.

TJPC adheres to rigorous international export standards, ensuring that every shipment undergoes thorough inspection before departure. This includes checks for uniform bale weight, intact packaging, accurate labeling, and secure pallet stability to guarantee optimal delivery conditions.

 The consistent and secure packaging of SBR 1712 supports seamless unloading, efficient warehouse storage, and smooth utilization by manufacturers across a wide range of industries.
