Sunresin developed food grade Seplite® LSF983 series of macroporous weak acid cation resin based on a polyacrylate matrix. The Seplite LSF983® is very suitable for hardness (calcium and magnesium) removal from potable water (household water filters, pitchers etc), beverage and food applications. Besides hardness, it can also help to reduce certain level of heavy metals as Copper, Lead etc.

The 20th World Pharmaceutical Raw Materials China Exhibition, CPhI China 2020, will take place from December 16th to 18th, 2020, at Shanghai New International Expo Center (SNIEC). As a provider of specialized separation and purification materials, system equipment and overall turn-key solutions, Sunresin New Materials Co. Ltd. will bring a professional team of around 20 people to this event, covering a wide range of fields including pharmaceutical separation and purification, herbal extraction, biological product purification, as well as wastewater and VOCs treatment, in order to better serve the pharmaceutical companies and contribute to the development of the industry as a whole.

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.

Sunresin has set up special topics and established a special research team based on customers’ needs to conduct research and analysis on the element composition and existing technology of tungsten leaching solution, and successfully developed sepcial resin Seplite® LSC680 for tungsten and molybdenum separation as well as the matching process. Through special pretreatment to the feed solution, the molybdenum in the solution will be highly selectively adsorbed on the LSC680 resin, while the tungsten remains in the solution after adsorption. The separation of tungsten and molybdenum can be realized in a simple and efficient manner.

The ion exchange resin (IER) method is very excellent and efficient for acetone purification. Acetone will pass cation exchange resins first and then the anion exchange resins, more than 95% methylamine will be removed.

On November 23, 2020，Forbes announced Asia’s Best Under A Billion 2019 list. Sunresin was honored to be selected. The promulgation ceremony originally scheduled to be held in Bangkok, Thailand, was carried out online due to continuous spreading pandemic.

Ethylene glycol (EG) is an important organic chemical raw material. It is mainly used to synthesize polyester polyester and polyester resin, produce hygroscopic agents, plasticizers, surfactants, cosmetics and explosives, and used as dyes, inks, solvent, formulating engine antifreeze, etc.

Application of Mixed Bed Ion Exchange ResinSEPLITE® Ion Exchange Resins are very versatile in their application: one of them is the use as a mixture of Cation and Anion exchange resins also known as Mixed Bed (MB). Mixed Beds allow to perform an efficient demineralization in one process step: by intimately mixing highly regenerated Cationic and Anionic resins a Mixed Bed represents a succession of a huge number of Cationic and Anionic exchanger beds leading to a very high purity of the treated water.
