About Us

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 their very first PTFE membrane in our own laboratory, and since then, we have been focusing on PTFE materials.

In 2000, JINYOU made a significant breakthrough in the film-splitting technique and realized the mass production of stronger PTFE fibers, including staple fibers and yarns. This breakthrough allowed us to expand our focus beyond air filtration to industrial sealing, electronics, medicine, and the clothing industry. Five years later in 2005, JINYOU established itself as a separate entity for all PTFE material research, development and production.

Today, JINYOU has received worldwide acceptance and has a staff of 350 people, two production bases respectively in Jiangsu and Shanghai covering 100,000 m² land in total, headquarters in Shanghai, and 7 representatives on multiple continents. We annually supply 3500+ tons of PTFE products and nearly a million filter bags for our clients and partners in diverse industries throughout the world. We have also developed local representatives in the United States, Germany, India, Brazil, Korea, and South Africa.


JINYOU's success can be attributed to our focus on PTFE materials and our commitment to research and development. 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. Our products have been widely adopted and trusted by clients and partners worldwide. We will continue to expand our reach on multiple continents.
