Import Accelerator Cz,Cbs — Buy in Bulk from Supplier in China

Accelerator CZ (N-cyclohexyl-2-benzothiazole sulfenamide) is a delayed-action vulcanization accelerator identified by CAS number 95-33-0 and EINECS number 202-411-2. This pale yellow or gray powder exhibits an initial melting point of 98°C, with heat loss capped at 0.3% and ash content limited to 0.3%. The residue on a 150-micron sieve is controlled to 0.05%, ensuring a consistent particle size distribution for uniform curing performance.

As a sulfenamide-class accelerator, CZ delivers a strong after-effect, enabling short curing times while maintaining excellent scorching resistance. This makes it particularly suitable for high-volume production environments where precision and repeatability are critical. The product is commonly packed in 25 kg kraft bags with an inner polyethylene liner, a standard for rubber chemicals to prevent moisture absorption and contamination.

Primary applications include tires, rubber tubes, shoes, tapes, and cables, where its balanced cure profile enhances physical properties without sacrificing processing safety. Buyers typically source this accelerator in bulk for industrial use, with packaging and handling tailored to maintain its stability during transit. Confirming compatibility with specific rubber compounds and processing conditions is advised before large-scale adoption.

Qingdao Rubber Auxiliary Chemicals Co., Ltd. operates from North Siliu Road in the Licang Area of Qingdao, Shandong Province, China. The company is classified under the harbor trust tier, reflecting its established presence in the rubber chemicals sector. While its response rate and average response time are currently unrecorded, its physical address and product specifications indicate a focus on industrial-grade accelerators and additives.

The supplier specializes in rubber processing chemicals, with Accelerator CZ, CBS being a core offering. Its product descriptions emphasize technical performance, such as curing efficiency and scorching resistance, which aligns with the demands of tire and rubber goods manufacturers. The company does not provide publicly verifiable details on certifications, production capacity, or client base, so buyers should request these directly.
