Who We Are

JINYOU is a technology-oriented enterprise that has been pioneering the development and application of PTFE products for over 40 years. The company was launched in 1983 as LingQiao Environmental Protection (LH), where we built industrial dust collectors and produced filter bags.

Through our work, we discovered the material of PTFE, which is an essential component of high-efficiency and low-friction filter bags. In 1993, we developed our very first PTFE membrane in our own laboratory, and since then, we have been focusing exclusively on PTFE materials.

Our expertise in PTFE has allowed us to develop innovative solutions for various industries, contributing to a cleaner world and making daily life easier for consumers.
