Jiangsu Jinkai Resin Chemical Co., Ltd

China is the origin of Jiangsu Jinkai Resin Chemical Co., Ltd, which currently lists five distinct chemical products. The company’s catalogue falls under the fabric softener and water treatment chemical categories. Its product list includes industrial and food‑grade softening agents as well as ion‑exchange resins for iron removal, biodiesel purification, and selective boron capture. All items are identified by internal product codes such as bc120, bc118, bd120fd, bc800, and bd501. The catalogue does not provide HS codes, so the products are generally classified under HS chapter 38 for organic chemicals and HS chapter 39 for polymeric resins.

The industrial grade softening bc120 is a cationic resin intended for textile fabric softening processes, while the food grade softening bd120fd meets food‑contact requirements. Iron removal resin bc118 is an anion exchange resin used in municipal and industrial water treatment to adsorb Fe2+/Fe3+ ions. Biodiesel purification bc800 is a specialized resin for removing glycerol, methanol and catalyst residues from biodiesel streams. Boron selective weak base anion resin bd501 targets boron removal in drinking water or process water applications. These five products represent the full active offering of the supplier as recorded.

Jiangsu Jinkai’s catalogue contains cationic softening resins and several anion exchange resins. In the fabric‑softener market, cationic resins are typically supplied in grades such as IEC 60715 class A or B, with bead diameters between 0.5 mm and 1.2 mm and exchange capacities of 1.2 - 2.0 meq g‑1. Food‑grade variants must comply with FDA 21 CFR Part 177 or EU Regulation 10/2011, limiting residual monomers and heavy metals to ≤10 ppm. Water‑treatment resins for iron removal or boron selectivity are usually weak‑base anion exchangers, specified by selectivity coefficients (e.g., KFe/Cl ≈ 30) and operating pH ranges of 2 - 8. Biodiesel purification resins are often cross‑linked styrene‑divinylbenzene polymers with pore volumes of 0.6 - 0.8 mL g‑1 and are designed to withstand temperatures up to 120 °C.

Typical specifications for these resin types also include a sodium form for regeneration, a moisture content below 8 %, and a bulk density of 0.6 - 0.8 g cm‑3 for efficient column packing. Standard packaging for bulk resin shipments is 25 kg polypropylene bags or 1 ton intermediate bulk containers, compatible with 20‑ft and 40‑ft containers. Buyers often request a certificate of analysis (CoA) that lists ion‑exchange capacity, bead size distribution, and impurity limits.
