Dongying Hysen Chemicals Co., Ltd. is a modern and environmental-friendly high-tech enterprise. We are mainly engaged in R&D, production and marketing of special ion exchange resin products. Meanwhile, we also provide application unit design of ion exchange resin, production of fine chemicals and support of water treatment equipment, and operate as an agent for foreign high-tech products in China.

Thanks to our many years' professional experience in design and development of functional polymers, a technical research center is established in Science Park of China University of Petroleum (UPC), a professional resin material test lab is established in the university and an industry-education-research platform is built by us based on Academy of Science and Technology of UPC. We have a high quality product R&D and application technology R&D team and have good cooperation ties with many Chinese and overseas universities and colleges and famous enterprises. Ion exchange resin production and dedicated fine-process units that are industry-leading in China are built here as well. In accordance with Chinese and overseas requirements of separation and refining technologies for new and special functional polymer materials, application technologies and products are provided for modern manufacturing industries as well as environment protection, energy-saving and quality upgrade of industrial technologies. Strong technical and product supports are provided for development of Hysen as well. Currently, we have eight series of resin products, i. e. Strong acid, weak acid, strong alkaline, weak alkaline, chelating, amphoteric, catalytic and adsorption resin products. More than one hundred iron exchange resin products are available, including: MR series mixed bed resin for low-speed wire-cutting electrical discharge machining tools; HP series high regeneration ready-to-use resin for hyper-pure water preparation; DL series resin for thermal power plant inner cooling water treatment; UPM-100 refined mixed bed resin for ultra-pure water for semiconductor industry; NR series nuclear grade resin, IDC series indicator (color) resin; NPW series powder resin for Powdex process of nuclear power plant and large-scale thermal power plant condensate fine processing, etc. These products deliver good application performance, large operation exchange capacity and high mechanical strength. Thanks to the premium price-performance ratios, our products have replaced many imported products and been widely used in many fields such as electricity, petrochemical, precision machining, food, pharmacy, biochemical, electronics, hydro-metallurgy and environment protection. With excellent product quality and service, we have won customers' credit and built a sound reputation and image of the company.

We have provided ODM services for overseas companies, and have become an appointed supplier for many large and medium engineering companies in China. We have integrated advanced foreign application technologies and exquisite processes into our product series, developed high-quality, fine and special iron exchange resin series products, and spared no efforts to establish Chinese resin industry!
