Since 2017, Sunresin has carried out research and development on BPA resins. From understanding the production process of bisphenol A to benchmarking against similar competition products, after thousands of experiments and demonstrations, the resins were be tested for the first time in 2022.

Sunresin’s VOCs treatment resin is a styrene-DVB matrix macroporous adsorption resin with a specially designed resin structure. It has a good mesh structure and a high specific surface area, and can be sieved through the size of the pores. Organic molecules are selectively adsorbed by interaction, intermolecular force or hydrogen bond interaction.

In Sunresin’s method, the hydrophobicity of the resin is further increased, the degree of crosslinking gets increased, and the pore structure gets adjusted. The adsorption resins have a narrow particle size distribution, uniform pore size and high specific surface area. As the size of micropores in the resin is close to the molecular size of perfluorooctanoate in water, which has a strong selectivity of the adsorbates and can therefore further increase the adsorption rate of perfluorinated compounds.

Sunresin is strongly supportive of the CO2 reduction as set in the Paris Climate Accord by enabling this growing Lithium demand for energy storage which will provide strong opportunities for its patented and proprietary equipment, solutions and services.

Sunresin recently developed Seplite LXA8101 a macroporous adsorbent based on a polymerized Styrene DVB matrix. The adsorbent has been so designed to offer a high capacity and can be used in the purification of many different herbal extracts. The pore size and surface characteristics of Seplite LXA 8101 have been optimized to offer a high selectivity and capacity for flavonoids & lactone, saponins, anthocyanin contained in the extraction liquor. Once saturated LXA8101 can be regenerated with alcohol or a caustic solution to start a new cycle. The polymer matrix has been optimized to provide good physical and chemical stability allowing for a long lifetime.

Organic synthetic polymer material is a kind of polymer material with certain functional properties, which is produced by the polymerization of unsaturated organic molecules with double bond structure under initiating conditions.

Seplite® LSC285 special resin for brine iodine removal, and developed a complete set of iodine removal process through the industrial scale verification of many domestic ion membrane caustic soda productionenterprises, the effect is remarkable. The iodine is effectively removed and the iodine recoveryis realized. It not only solves the problem of electricity efficiency, but also creates economic benefits, which is highly praised and recommended by industry and enterprises.

In the face of the industry problem of the treatment of chlorinated hydrocarbon waste gas, Sunresin creatively introduces resin adsorption technology to the treatment of chlorinated hydrocarbon waste gas. Using the high selective adsorption between the special resin skeleton molecule and the chlorinated hydrocarbon molecule, combined with the complex pore structure design inside the resin, it realizes the efficient adsorption and interception of chlorinated hydrocarbon molecule in the waste gas, and carries out resource recovery. Industry verification shows that the recovery rate of adsorption and removal of chlorinated hydrocarbon molecules by Sunresin's special resin and supporting treatment device of waste gas treatment is over 99%, and the export is stable and up to standard. The products and technologies of waste gas treatment resin have been widely recognized by relevant enterprises.
