Sunresin New Materials Co. Ltd.’s issuance of convertible corporate bonds to unspecified objects has been approved by the China Securities Regulatory Commission in March 2023.

Sunresin's premium resins excel in eliminating impurities from the leaching solution, marking a significant reduction of TOC (residual P204, P507, sulfonated coal oil, etc.), COD (Chemical Oxygen Demand). This method is not only efficient but also environmentally conscious, ensuring no new impurities are introduced. The result? Enhanced economic value and benefits.

Advantages of Resin Adsorption: -Environmental-friendly and low energy consumption, operating under ambient temperature and pressure conditions. -Sunresin's chelating resin demonstrates excellent performance in the extraction of precious metals such as cobalt, vanadium, platinum, palladium, and gold. It not only achieves the requirements for the wastewater maximum content of metals but also enables the recovery of high-concentration metal salt solutions. -The resin has very high adsorption capabilities across different concentrations of mother liquor, with minimal impact from the ionic form of platinum and palladium. It operates stably under various pH conditions, facilitating the recovery of precious metals. In the field of platinum catalyst recovery in the pharmaceutical industry, this resin series offers high processing precision and large adsorption capacity compared to traditional recovery processes.

We are very proud to announce that Dr Simona Serban has joined Sunresin as Global Application Director for Life Science division. Simona comes with more than a decade experience in applications of resins in the Life Science

In concentrated hydrochloric acid, metal ions mainly exist in the form of complex anions. LSC series ion exchange resins can effectively remove iron ions and also remove other metal ions to varying degrees. Contaminated hydrochloric acid passes through a special ion exchange resin, and the exchange process capture the iron thanks to the very high selectivity. Once the LSC series ion exchange resin is saturated with iron ions, it can be regenerated with deionized water (distilled water). After regeneration, the ion exchange resin is restored to its original state and can be repeatedly used for exchange and regeneration.
