Jiangsu Jinkai Resin Chemical Co., Ltd supplies the BD501 boron-selective weak base anion resin, engineered for targeted boron extraction from aqueous streams. The resin is formulated with a styrene-divinylbenzene matrix and functionalized with amine groups that bind boron in the form of boric acid complexes. Its volume exchange capacity is specified at 5.0 mg/mL, indicating a high density of active sites per unit volume.
The resin operates effectively in pH ranges from 6 to 8, where boric acid predominates as B(OH)3, enabling selective chelation. It exhibits minimal interference from common anions such as sulfate and chloride, making it suitable for use in high-salinity environments. Unlike strong base resins, BD501 does not require caustic regeneration, reducing chemical consumption and waste volume. Its mechanical stability supports use in high-flow applications without significant attrition.
Applications include boron removal in semiconductor cooling water, nuclear plant effluents, and irrigation systems in arid regions. Buyers in the power generation and electronics industries use this resin to meet strict discharge limits of 0.5 mg/L or lower. The resin is packaged in 25 kg sealed polyethylene bags with moisture barrier lining. MOQ and lead time are not stated in the listing and must be confirmed directly with the supplier.

Jiangsu Jinkai Resin Chemical Co., Ltd. is based in Yancheng, Jiangsu Province, and operates as a manufacturer of specialty ion exchange resins for industrial water treatment. The company is listed as an imported supplier with harbor-level trust verification, indicating compliance with export documentation protocols. Its profile does not include company history, workforce size, revenue, or client references, and no certifications are stated beyond product performance data.
The firm specializes in boron-selective and other targeted resins for niche applications, suggesting focused technical capability. It does not appear to offer a broad range of standard resins. The absence of response rate data implies limited buyer interaction, but the technical specificity of BD501 suggests internal R&D activity. Buyers should request independent test reports to validate capacity and selectivity claims before procurement.

Verify the resin’s actual exchange capacity and selectivity against your water matrix before ordering. Request a batch-specific certificate of analysis showing test results for boron adsorption, chloride interference, and particle size. Do not rely on catalog claims without third-party validation. Confirm that the resin is free from residual solvents or contaminants from manufacturing.
Lead time and delivery terms are not specified in the listing. Confirm whether the resin is shipped under FOB, CIF, or EXW terms and whether customs clearance is included. Payment methods such as T/T or L/C are common, but terms must be negotiated directly. Ask for the exact packaging weight and dimensions to plan storage and handling.
Upon delivery, inspect the bags for moisture, tears, or discoloration. Retain a sealed sample from each batch for future testing. Conduct a regeneration test to confirm capacity retention. Request a batch traceability number and ensure it is documented on all shipping and compliance paperwork. If performance falls short, document deviations and initiate a claim promptly.
