     Established in 2013 in Linyi County, Dezhou City, Shandong Province, it is a company that integrates scientific research

A high-tech enterprise that integrates the development, production, and sales of fluorine resin throughout the entire industry chain

. The company extends its core focus on high-end fluorine materials to lithium battery new energy, photovoltaic new energy, semiconductors, high-end coatings, aerospace, military and other fields. 2018

The company has signed a strategic cooperation agreement with Tsinghua Institute of Technology, relying on its strong capabilities

With a large R&D team and technical background, we have achieved leapfrog development in our main product PVDF resin, and quickly completed more than ten products in three major series: lithium battery, extrusion, and coating

Level R&D and layout, establish strategic partnerships with leading companies in various fields.

The company currently has an annual production unit of 5000 tons of polyvinylidene fluoride (PVDF) and corresponding supporting equipment, which can simultaneously produce lithium grade, photovoltaic grade, and coating grade

PVDF products, with a current lithium grade PVDF production capacity of 3000 tons/year, planned for 2022

Expand production to 10000 tons/year (including 2000 tons/year diaphragm level production capacity).
