Who we are JINYOU is a technology-based company pioneering the development and application of PTFE products for over 40 years. The company was founded in 1983 as LingQiao Environmental Protection (LH), where we built industrial dust collectors and produced filter bags. Through our work, we discovered PTFE, which is a key component of high-performance and low-resistance filter bags. In 1993, we developed our first PTFE membrane in our laboratory, and since then, we have been focusing on PTFE materials.
