As the first domestic ion-exchange membrane manufacturer who developed continuously calendering membrane forming technology on its own, Liaoning Yichen Membrane Technology Co.,Ltd. made its debut on 2017 (the sixth) Guangzhou International Water Treatment Expo, communicating and exchanging ideas in depth with other exhibitors and visitors from mainland China, America, Japan, Korea, Taiwan China, Italy, Germany, and other countries and areas.

Our ion-exchange membrane products are developed on our own with our continuously calendering membrane forming technology which is d on complex thermoplastic ion-exchange resin that contains vinyl fluoride and polystyrene. With a higher accuracy of membrane thickness controlling, the flexible structure unsupported by reinforcement is compatible with all kinds of electrodialysis spacers including the kind designed for polypropylene heterogeneous membranes. We made the first domestic bipolar membranes and provided a reliable source of high-quality bipolar membranes, which made us a major enterprise in the industry who has fully grasped the core technology of large-scale industrialized mass production. Many visitors visited our booth, learned and inquired about our products, and gave us a high level of praise and recognition to our technology.

The application of ion-exchange membrane technology is an advanced method of dealing with environmental pollution, playing a key part in waste acid and alkali solution treatment that can be done by no other membranes. Because of its special properties, ion-exchange membrane can be used for the separation and classification of ionic system, which is extremely significant in cleaner production, environment protection, energy transformation and other fields. It especially meets the demands of energy-saving and low-grade raw material recycling, and pollution preventing in modern industry. It is an essential part of the sustainable economic development strategy, meeting multifaceted demands like water recycling and treatment, environment protection, and clean production in many countries.
We endeavor to provide high-efficiency, energy-saving wholesome solutions to waste water desalination and saline concentration in llurgical  industry, petrochemical industry, coking industry, and papermaking industry with our ion-exchange membranes, solve a series of major problems from waste discharge, resource recycling to zero discharge faced by some enterprises, and finally achieve the innovative idea of “purify life with science, and enjoy a green life”.
