Our factory began producing and developing chemical packing materials in the early 1970s. We currently offer over 100 varieties across two main series: random dumped and structured packings. Primary metal materials include: pure titanium, aluminum alloy, stainless steel, carbon steel, and bronze. Plastic materials include: PVDF, CPVC, PVC, PP polytetrafluoroethylene, nylon, and others. These products are widely used in industries such as chemical engineering, fertilizers, caustic soda, petrochemicals, power generation, and pharmaceuticals, playing a role in enhancing efficiency and reducing consumption, thereby providing enterprises with substantial comprehensive economic benefits.

Our factory consistently adheres to the principle that quality is the life of the enterprise and the customer is our priority. We have established long-term technical cooperation agreements with 10 domestic chemical research institutions and design institutes, and employ senior technical management professionals. From product development, production, and testing to after-sales service, we implement a comprehensive and rigorous management system that includes feedback mechanisms. The enterprise obtained ISO9002 international certification in early 2000 and has been recognized as a municipal-level unit that honors contracts and maintains credibility.
