About Zhengzhou Double Vigour Chemical Product Co., Ltd. - Rubber Chemicals Supplier in China

Zhengzhou Double Vigour Chemical Product Co., Ltd. is based in China and lists nine active products in its catalogue. All nine items belong to the rubber chemicals segment and are described as accelerators or antioxidants used in vulcanisation processes. The product titles include Rubber Accelerator‑ZMBT, MBT (2‑Mercaptobenzothiazole), MBTS (Dibenzothiazole disulfide), CBS, TMTD (Tetramethyl‑thiuram‑Dis), and polymerised TMQ antioxidant, plus generic entries for rubber antioxidant and accelerator‑MBTS. Each product name follows the standard industry nomenclature for sulfur‑donor and sulfur‑scavenging agents that control cure rate and ageing of rubber compounds. The catalogue does not provide HS codes, so the products are grouped under the broader HS chapter 40 for rubber chemicals.

The supplier’s catalogue focuses exclusively on chemical additives that modify the cure kinetics and oxidative stability of natural and synthetic rubber. Accelerators such as ZMBT, MBT, MBTS, CBS and TMTD are typical low‑molecular‑weight compounds that act as sulfur donors, while antioxidants like TMQ protect against ozone and heat‑induced degradation. The listed items are supplied in bulk powder or granulate form, which is the common physical state for these additives. No additional product families beyond accelerators and antioxidants are mentioned, indicating a specialised portfolio within the rubber chemicals market.

Product Range and Specialties of Zhengzhou Double Vigour Chemical Product Co., Ltd.

The nine listed items comprise four primary accelerator families (zinc‑based, thiazole‑based, dithiocarbamate‑based and thiuram‑based) and two antioxidant types. In the rubber industry, accelerators are often graded by activity level, solubility and thermal stability, with specifications such as purity > 98 % and moisture < 0.5 %. Antioxidants like TMQ are typically evaluated for oxidation induction time and concentration limits (e.g., 0.5 - 2 % w/w in the compound). Buyers commonly encounter these chemicals under HS codes 3808.10 (rubber accelerators) and 3808.90 (other rubber chemicals). Typical grades include technical‑grade (≥95 % purity) for bulk applications and fine‑grade (≥99 % purity) for high‑performance tires.

Trade and Export Information - Zhengzhou Double Vigour Chemical Product Co., Ltd.

China is a major exporter of rubber chemicals, supplying accelerators and antioxidants to tyre manufacturers in Southeast Asia, Europe and North America. The HS‑8 heading 3808 covers these products, and customs authorities often require a Certificate of Origin and compliance with REACH for shipments to the EU. Importers usually request safety data sheets (SDS) and third‑party test reports that reference ASTM D 1500 (rubber accelerator purity) or ISO 11357 (thermal analysis). Shipping is typically performed in 20‑ft or 40‑ft containers with moisture‑resistant liners, using Incoterms such as FOB or CIF. Export licensing in China for chemical commodities follows the Ministry of Commerce regulations, and bulk shipments may be subject to inspection under the China Inspection and Quarantine (CIQ) system.

Buyers sourcing rubber chemicals from China often look for ISO 9001 quality management certification and REACH registration status, although the supplier’s own certifications are not listed in the facts. Standard documentation includes a commercial invoice, packing list, material safety data sheet, and a test certificate confirming purity, moisture content and particle size distribution (e.g., < 200 µm).

Sourcing from Zhengzhou Double Vigour Chemical Product Co., Ltd. - Buyer Guidance

When evaluating Zhengzhou Double Vigour Chemical Product Co., Ltd., request the latest safety data sheet for each accelerator or antioxidant to verify handling and transport requirements. Ask for a third‑party analytical certificate that details purity, moisture level and any residual metal content, as these parameters affect cure control and final product performance. Confirm whether the chemicals are REACH‑registered for EU destinations and whether the supplier can provide an ISO 9001 audit report, which is a common prerequisite for large‑scale tyre manufacturers. Verify packaging specifications - typically multi‑layered polyethylene bags within a bulk container - to ensure protection against humidity and contamination during transit.

Before placing an order, compare the supplier’s technical data sheets with the typical specifications for the intended rubber compound (e.g., accelerator activity expressed in mg g‑1 of rubber, antioxidant oxidation induction time). Establish a minimum order quantity that aligns with container loading efficiency (usually 10‑15 tonnes per 20‑ft container for powder accelerators) and confirm lead times, which for Chinese chemical exporters range from 3 to 6 weeks after order confirmation.

What types of rubber chemicals does Zhengzhou Double Vigour Chemical Product Co., Ltd. offer?

The supplier lists nine products, all classified as rubber accelerators (ZMBT, MBT, MBTS, CBS, TMTD) or rubber antioxidants (TMQ and a generic antioxidant).

Are HS codes provided for the listed products?

The catalogue does not include specific HS codes, but the products fall under HS chapter 40, commonly under headings 3808.10 for accelerators and 3808.90 for other rubber chemicals.

Which certifications should a buyer request from this supplier?

Buyers should request a safety data sheet, a third‑party purity test certificate, and confirmation of REACH registration. If available, an ISO 9001 quality management certificate is also useful.

What standard test methods are used for rubber accelerators?

Typical test methods include ASTM D 1500 for purity and moisture content, and ISO 11357 for thermal stability. Results are usually expressed as percentage purity and moisture %.

What packaging format is common for these chemicals?

Accelerators and antioxidants are usually supplied in moisture‑resistant polyethylene bags, stacked inside a bulk container (20 ft or 40 ft) with inner liners to prevent moisture ingress.

What are typical lead times and minimum order quantities for these products?

Lead times from Chinese chemical exporters generally range from three to six weeks after order confirmation. Minimum order quantities often correspond to container loads, roughly 10‑15 tonnes per 20‑ft container for powder‑type accelerators.

Which regions import rubber chemicals from China most frequently?

Major import regions include Southeast Asia (Thailand, Malaysia), Europe (Germany, Italy) and North America (USA, Canada), where tyre manufacturers and rubber compounders source accelerators and antioxidants.

What documentation is required for customs clearance of rubber chemicals?

Customs typically require a commercial invoice, packing list, Certificate of Origin, safety data sheet, and a test certificate confirming product specifications. For EU shipments, REACH compliance documentation is also mandatory.
