Import Best Selling Rubber Accelerator Pz — Buy in wholesale FOB from Supplier in China

Rubber Accelerator PZ, also known as zinc dimethyldithiocarbamate (ZMDC), is a ultra-fast primary accelerator for natural and synthetic rubber vulcanisation, supplied as a white powder or granule with a density of 1.66 g/cm3. The product exhibits solubility in dilute alkali and carbon disulfide (CS2), characteristics that influence its incorporation into rubber compounds and its behaviour during processing. As a dithiocarbamate class accelerator, it provides extremely rapid vulcanisation with short scorch time and high crosslink density, making it suitable for thin-walled articles and applications where fast curing is economically critical. The supplier markets this as a best-selling formulation, though batch-to-batch variation in melting point and purity should be confirmed through certificate of analysis.

The chemical structure of PZ features a zinc cation coordinated with two dimethyldithiocarbamate anions, conferring excellent solubility in rubber polymers and low critical vulcanisation temperature. Typical industry applications include latex dipped goods, threads, cements, and moulded rubber products where rapid curing at moderate temperatures is required. In tyre manufacturing, PZ is rarely used alone due to its scorch sensitivity, but serves as a secondary accelerator in combination with thiazoles or sulphenamides to boost cure rate and improve state of cure. The non-toxic claim in the source description requires verification against current REACH, FDA, or specific market regulations, as dithiocarbamates can decompose to yield secondary amines and nitrosamines under certain conditions. Standard packaging for this chemical category is 25 kg net weight in kraft paper bags or woven polypropylene sacks with polyethylene liner, though the supplier's exact packaging specification must be confirmed.

Primary buyers include manufacturers of rubber gloves (especially latex and nitrile), condoms, rubber threads, balloons, and various moulded technical rubber goods. The compound is also used in adhesive formulations and as a stabiliser in some polymer systems. Trade terms offered include FOB and CIF with payment by L/C or T/T, but specific pricing, minimum order quantities, and lead times are not provided in the source and must be negotiated directly. Buyers should request a technical data sheet specifying melting point range (typically 240-248 degrees Celsius for pure ZMDC), zinc content, and residue on 63 micron sieve, as these parameters govern dispersion behaviour and final article performance.

Zhengzhou Double Vigour Chemical Products is located in Zhengzhou City, Henan Province, China, with postal address Zhengzhou 450000. The supplier carries an imported-tier classification and a harbor trust tier. The response rate is recorded at 0.00 percent with zero average response hours, suggesting that the company has not yet engaged through the platform's enquiry system or that response data has not been captured. Buyers should not assume unresponsiveness but should initiate contact early and follow up through multiple channels including the listed address in Henan Province.

The company's name indicates specialisation in chemical products for the rubber industry, though the source provides no information about establishment year, production capacity, quality management certifications, or export experience. Henan Province hosts several chemical industrial zones, but the specific manufacturing location of this accelerator (whether produced in-house or sourced and repacked) is not disclosed. The source description contains marketing claims including 'non-toxic' and 'high-performance' that should be substantiated with safety data sheets, REACH registration status, and third-party test reports. Buyers should request the supplier's business licence, chemical production licence if manufacturing, and any ISO 9001 or ISO 14001 certifications that may apply.
