从China供应商批发进口Accelerator Nobs(Mor) — FOB条款

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.

Qingdao Rensheng Huida Trading Co., Ltd. is based in Qingdao, Shandong Province, with its registered office at Room 4003, Block B, 226# Mid Changjiang Road. The company operates as an importer of rubber chemicals and additives, focusing on the distribution of accelerators, antioxidants, and other compounds for industrial applications. Its profile indicates a specialization in serving manufacturers in the automotive and industrial rubber sectors.

The supplier holds a harbor trust tier, which reflects a baseline level of verification for export capabilities. While the response rate and average response time are currently not available, the company’s address and operational focus suggest a structured approach to trade. Buyers are advised to verify current certifications, as the listing does not explicitly state active ISO or SGS compliance for this specific product batch.
