General Information
JIANGYIN HAIDA RUBBER AND PLASTIC CO., LTD., headquartered in Jiangyin, Jiangsu Province, China, is an industry-leading enterprise specializing in engineered rubber products. Established in the engineered rubber sector in 1997, the company began independently developing shield segment sealing products in 2000 under the Haida brand. Today, Haida has grown to become the world’s largest supplier of sealing systems for shield tunnel segments, recognized for its outstanding technical strength, large-scale production capacity, and superior product quality. The company operates on a global scale, serving extensive domestic networks across China and an expanding international market that includes Singapore, Georgia, South Africa, India, Indonesia, Nepal, Malaysia, Sri Lanka, Bangladesh, and Panama.
Business Sector
Haida’s core business revolves around the research and development (R&D), manufacturing, and global sales of modified rubber-plastic materials. The company’s primary operational focus is divided into two key functional sectors: advanced sealing and anti-vibration system solutions. These specialized engineering materials and components are designed to support and supply four major industrial and infrastructure sectors: rail transit, building construction, automotive, and marine.
Application
The company’s technologies are practically applied to ensure critical waterproofing, sealing, and structural integrity in complex civil and geotechnical engineering projects. Haida’s solutions are predominantly utilized in underground and mechanized tunneling environments. They are heavily deployed in shield-driven excavations, resolving complex sealing challenges for urban metro railways, large-scale highway and railway river-crossing tunnels, water-diversion tunnels, power utility tunnels, and gas transmission infrastructure. Furthermore, their advanced waterproofing materials are specifically applied to manage extreme geotechnical conditions, such as high-water-pressure shield tunnels with excavation diameters exceeding 10 meters.
Products
- Shield Tunnel Segment Sealing Systems: Industry-leading sealing products designed for shield-driven tunnel segments, with a cumulative supply exceeding 5 million rings (approximately 7,500 kilometers of tunnel length) worldwide.
- High-Water-Pressure Waterproofing Materials: Specialized waterproof components engineered for large-diameter (over 10 meters) shield tunnels, currently holding a nearly 90% market share for these applications in China.
- Anti-Vibration Systems: Advanced rubber and plastic components formulated to provide structural vibration mitigation across transit, marine, and construction applications.
- Modified Rubber-Plastic Components: Core engineered materials tailored to deliver reliable, long-term sealing performance across various heavy industry and infrastructure sectors.
