Accelerator Ns, chemically known as N-tert-butyl-2-benzothiazole sulfenamide (TBBS), is a primary accelerator used in the vulcanization of natural and synthetic rubber. Its molecular structure, C12H14N2S2, provides a balance of fast cure rates and delayed scorch, making it a versatile choice for a broad selection of rubber products. The accelerator is particularly effective in tire compounds, where it enhances heat resistance and dynamic performance.
This product is supplied as a light gray to white powder with a typical melting point of 105-110°C and a density of approximately 1.26 g/cm³. TBBS is known for its high purity, which ensures consistent performance in rubber formulations. It exhibits low volatility and minimal bloom, reducing the risk of surface defects in finished goods. Industry standards often cite its ability to improve tensile strength and abrasion resistance in vulcanized rubber.
Manufacturers in the automotive, aerospace, and industrial sectors rely on TBBS for producing high-durability rubber components such as tires, conveyor belts, and vibration dampeners. Bulk supply is common, with packaging typically consisting of 20 kg or 25 kg bags lined with polyethylene to prevent moisture exposure. Buyers should confirm the exact packaging specifications and storage recommendations to maintain product integrity.

Before placing an order with Shijiazhuang Kunmai Chemical Technology Co., Ltd., confirm the product’s compliance with relevant standards, such as ISO 9001 or REACH. Request a certificate of analysis (COA) to verify purity, melting point, and absence of impurities. For critical applications, ask for third-party test reports to validate performance in tensile strength and heat resistance tests.
Clarify the Incoterms, with FOB Shijiazhuang being a common option for this supplier, and agree on lead times, which may vary based on order volume. TBBS is typically shipped in 20 kg or 25 kg bags, so ensure your storage facilities can accommodate these quantities. Discuss payment terms, as Chinese suppliers often prefer secure methods like letters of credit for new buyers.
Upon delivery, perform quality checks by testing the accelerator’s melting point, purity, and solubility. For rubber applications, conduct a small-scale vulcanization test to confirm scorch time and cure rate. Request the material safety data sheet (MSDS) and technical data sheet (TDS) to ensure the product meets your specifications and regulatory requirements for safe handling and use.
