About Zhengzhou Double Vigour Chemical Products - Rubber Chemicals Supplier in China

China hosts 15 active rubber‑chemical products listed by Zhengzhou Double Vigour Chemical Products. The catalogue spans antioxidants such as IPPD and TMQ, vulcanizing agents like DTDM, a series of thiazole‑based accelerators (BT, MBTS, CZ, EZ, PZ, M, M Sodium Salt) and other specialty chemicals identified under the HS‑2930 family for organic chemicals. One entry, Accelerator M Sodium Salt, is recorded with HS code 2930.90 and material description Sodium 2‑Mercaptobenzothiazolate (C7H4NNaS2). All items fall within the broader “Rubber Chemicals” and “Chemicals & Allied Products” categories indicated in the supplier’s top categories. The product set reflects typical functions required in tire and rubber manufacturing: antioxidants to inhibit oxidative degradation, vulcanizing agents to promote cross‑linking, and accelerators to control cure rate. Each product is listed by its trade name only, without additional specifications such as purity or packaging size. The supplier’s tier is listed as imported with a harbor trust tier, indicating it operates through standard Chinese export channels.

Product Range and Specialties of Zhengzhou Double Vigour Chemical Products

The catalogue includes antioxidants (IPPD, TMQ), a dithiocarbamate vulcanizing agent (DTDM), thiazole‑based accelerators (BT, MBTS, CZ, EZ, PZ, M, M Sodium Salt) and other rubber chemicals (DPG, MZ, NS, DPG). In the rubber‑chemical industry, antioxidants are typically supplied at 98‑99 % purity and graded by ICUMSA‑like standards for color and impurity limits; common dosage ranges are 0.2 - 1.5 parts per hundred rubber (phr). Accelerators such as MBTS or CZ are usually offered in powder form with particle sizes below 200 µm and activity measured by TGA (Tensile Gauge Acceleration) values between 0.8 and 1.2 MPa. Vulcanizing agents like DTDM are graded by active sulfur content, often above 85 %. Typical packaging for these chemicals in China includes 25 kg paper bags or 1 ton bulk drums, sealed to meet UN 1993 transport classification for hazardous organic substances. Buyers frequently request material safety data sheets (MSDS) and certificates of analysis (CoA) that specify moisture content (<0.5 %), heavy‑metal limits (≤10 ppm Pb), and thermal stability data.

Trade and Export Information - Zhengzhou Double Vigour Chemical Products

China is a leading exporter of rubber chemicals, supplying Southeast Asian tire producers, European automotive rubber compounds manufacturers, and North American specialty rubber formulators. The HS‑2930 chapter covers organic chemicals such as mercaptobenzothiazolate salts; customs authorities often require REACH registration evidence and a valid MSDS for each shipment. Standard export logistics involve 20‑foot or 40‑foot containers with FCL (full container load) or LCL (less than container load) options, typically under FOB Shanghai or CIF target ports in Vietnam, Thailand, Germany, or the United States. Importing countries generally inspect for compliance with ISO 9001 quality management, REACH registration, and, where applicable, OHSAS 18001 occupational safety standards. Documentation commonly includes a commercial invoice, packing list, certificate of origin, and test reports confirming antioxidant activity (e.g., DPPH assay) or accelerator efficacy (e.g., scorch time reduction).

Sourcing from Zhengzhou Double Vigour Chemical Products - Buyer Guidance

Buyers should request a detailed product data sheet that lists purity, moisture, heavy‑metal limits, and recommended dosage ranges before placing an order. Requesting a recent CoA and an MSDS for each chemical is standard practice; these documents verify compliance with REACH and allow the buyer’s quality lab to run confirmatory HPLC or GC‑MS tests. Sampling is typically offered in 5 kg or 10 kg quantities, packaged in sealed polyethylene bags. Verify that the supplier can provide container sealing certificates and that the packaging meets UN 1993 requirements for hazardous organic chemicals. Confirm lead times (often 15‑30 days for stocked items) and the Incoterm that will be applied to ensure clarity on freight and insurance responsibilities.
