Frequently Asked Questions
In which industry sectors is Emulsion Styrene-Butadiene Rubber (ESBR) primarily used?
Emulsion Styrene-Butadiene Rubber (ESBR) is heavily concentrated in the tire industry and serves as a key material for passenger car, truck, and off-road tire treads. It primarily provides wear resistance and wet‑skid resistance and is often blended with natural rubber. It is also widely used in industrial and consumer products such as conveyor belts, hoses, and shoe soles, meeting their common requirements for abrasion resistance and aging resistance.
How do ESBR and Natural Rubber (NR) differ in their roles within tire tread compounds?
Natural Rubber (NR) exhibits outstanding tear resistance and fatigue resistance due to its strain-induced crystallization, making it essential for tire toughness. ESBR, produced through industrial synthesis, offers stable performance, and its molecular chain structure and polarity provide excellent wear resistance, durability, and wet‑skid resistance, ensuring tire longevity and safety. The synergistic blending of the two effectively balances overall tire performance.
What differentiates high‑bound grades (ESBR 1737/1739/T0143/T0150) from other ESBR grades?
The key advantage of high‑bound grades (ESBR 1737/1739/T0143/T0150) lies in their superior wet‑skid resistance. By increasing the styrene bound ratio, the molecular chains exhibit enhanced low‑temperature dynamic performance, significantly improving wet‑skid resistance for high‑performance tire applications. Other grades (with approximately 23.5% bound styrene) focus on balanced overall performance, providing good abrasion resistance and processing stability, making them reliable choices for general‑purpose tires and rubber products.
What should be noted during the processing of high‑bound grades (ESBR 1737/1739/T0143/T0150)?
When processing high‑bound grades, special attention should be given to compounding conditions and the vulcanization system. Due to the higher styrene bound ratio, the initial compound viscosity is relatively high. Mixing steps and temperatures may be optimized as needed to ensure uniform dispersion of fillers and oils, preventing impacts on final product quality. Additionally, changes in molecular chain reactivity may lead to slower vulcanization rates, so adjustments to accelerator dosage and ratios can help achieve appropriate processing safety and optimal vulcanization efficiency.
Do ESBR products comply with the EU restrictions on chemical substances?
We closely monitor relevant regulations and ensure compliance through supply chain management and production process control. Our products meet the restrictions on Substances of Very High Concern (SVHC) under Article 57 of the EU REACH Regulation, as well as the requirements of Annex XVII, Item 50 concerning eight types of Polycyclic Aromatic Hydrocarbons (PAHs).
Which system certifications have the ESBR manufacturing plants obtained?
Our plants are certified to IATF 16949 for automotive quality management systems, ISO 14001 for environmental management, ISO 50001 for energy management, ISO 45001 for occupational health and safety management, and ISCC PLUS for international sustainability and carbon certification. Carbon footprint assessments are conducted in accordance with ISO 14064‑1.
