Luoyang De-dao Plastics Science & Technology Co., Ltd., established in May 2008, is a designated technology-based enterprise headquartered in the Luoyang, China (Henan) Pilot Free Trade Zone. Operating with a registered capital of 36 million yuan, the organization integrates a municipal-level research and development center recognized by the National Science and Technology Bureau. Driven by a core vision to become a benchmark enterprise in China’s vacuum preloading sealing film industry, De-dao Plastics adheres to the operational values of integrity, innovation, dedication, and cooperation. The company has actively led industry standardization by issuing the Q/LYDD001-2018 enterprise standard in 2018 and adopting advanced, intelligent production control systems in 2022 to ensure high-quality output and mutual benefit for its clients.
Business Sector
The company operates primarily within the geotechnical materials manufacturing and research and development (R&D) sectors. De-dao Plastics specializes in the development, intelligent production, and standardization of vacuum preloading plastic sealing films, maintaining an annual production capacity of 10,000 tons. Their operations encompass a highly controlled production and testing lifecycle, including raw material physical and chemical analysis, high stirring kneading, extrusion molding, heat sealing processing, and rigorous finished product performance testing.
Application
The specialized technologies and polymer films developed by De-dao Plastics are fundamentally applied to soft foundation treatment in major infrastructure and national key projects. These advanced sealing films are engineered specifically for vacuum preloading engineering applications, providing essential ground consolidation solutions for demanding construction environments such as extensive land reclamation projects, the development of ports and docks, and large-scale highway construction.
Products
The company’s flagship offerings include:
- PVC Vacuum Preloading Sealing Film: A new-generation geotechnical product manufactured via a specialized blow molding method utilizing a unique GFZ-7626 polymer material formula.
- High-Strength & Low-Shrinkage Sealing Film: Engineered for enhanced tensile strength and toughness, featuring a significantly reduced shrinkage (rebound) rate of 0.2% to 0.5%, compared to the standard 2% to 3% rate found in ordinary vacuum films.
- Low-Permeability Sealing Film: Designed with a highly compact molecular structure that achieves a smaller permeability coefficient, optimizing vacuum retention during foundation treatment.
- Anti-Aging UV-Resistant Sealing Film: Incorporates a specialized anti-aging agent capable of shielding 80% to 90% of ultraviolet sunlight during field use, drastically improving performance and extending the service life of the material in exposed engineering environments.
