Accelerator NOBS, also known as N-oxydiethylene-2-benzothiazole sulfenamide, is a delayed-action sulfenamide accelerator designed for natural and synthetic rubber compounds. This product delivers controlled scorch safety with rapid cure rates, making it ideal for thick rubber articles where heat buildup is a concern. The chemical formula C11H12N2O2S2 ensures compatibility with a broad selection of elastomers, including NR, SBR, and BR, while its molecular structure provides stability during high-temperature processing.
The accelerator appears as a light yellow to white powder with a melting point typical for sulfenamides, around 80-85°C, and a density of approximately 1.35 g/cm³. It offers low volatility and minimal bloom, which reduces surface staining in finished products. NOBS is particularly valued in tire manufacturing for its ability to improve tensile strength and elongation without compromising aging resistance. Industry-standard tests confirm its effectiveness in reducing cure time by 10-15% compared to conventional accelerators.
Manufacturers of automotive tires, conveyor belts, and industrial hoses use NOBS to achieve consistent vulcanization across complex shapes. Bulk packaging typically includes 25 kg multiwall paper bags with polyethylene liners to prevent moisture absorption. Buyers should confirm packaging specifications, as variations may occur based on order volume. The product is suitable for applications requiring compliance with automotive and industrial rubber standards, including ASTM D412 for tensile testing.

Before ordering NOBS from Qingdao Rensheng Huida Trading Co., Ltd., verify the batch-specific certifications, such as ISO 9001 or SGS, to ensure compliance with your industry standards. Request a certificate of analysis (COA) to confirm the product’s purity, melting point, and absence of contaminants. It is also prudent to check if the supplier can provide third-party test reports for critical properties like scorch time and cure rate.
Confirm the logistics details, including Incoterms (FOB Qingdao is common for this supplier), lead time, and port of loading. NOBS is typically shipped in 25 kg bags, so ensure the packaging meets your handling and storage requirements. Discuss payment terms upfront, as Chinese suppliers often prefer irrevocable letters of credit or telegraphic transfers for first-time buyers.
Conduct quality checks upon receipt by testing the accelerator’s melting point, density, and solubility in standard solvents. For rubber applications, perform a small-scale vulcanization test to validate scorch safety and cure characteristics. Request documentation such as the material safety data sheet (MSDS) and technical data sheet (TDS) to ensure the product meets your specifications and regulatory requirements.
