In January 2026, Dalian Bohai Rubber & Plastic Co., Ltd. (hereinafter referred to as “Bohai Rubber & Plastic”) announced its continued deepening of its business layout in the automotive sealing ring sector. Through technological upgrades and capacity expansion, the company aims to fully meet the demands of the automotive industry. This strategic focus by Bohai Rubber & Plastic is intended to drive collaborative innovation across the industrial chain with high-performance sealing solutions.
Leveraging years of R&D experience, we have comprehensively refined and expanded our product portfolio. Our seal products include EPDM, NBR, HNBR, FKM, and AEM seals. In particular, our perfluoroelastomer seals maintain stable performance even in extreme environments at 200℃, while also meeting flame-retardant standards. This effectively addresses the risk of leakage under high-temperature operating conditions, providing critical assurance for vehicle safety.
For many years, Bohai Rubber & Plastics has established deep partnerships with several leading automakers, offering integrated solutions tailored to the sealing needs of body-in-white sheet-metal holes.
To meet the rapidly growing market demand, we continue to invest heavily in production lines and technological development capabilities. We have added a fully automated vulcanization production line and advanced precision testing equipment, enabling closed-loop management across the entire process—from raw materials to finished products. By introducing a vision inspection system, we’ve boosted our product yield to 99.8% and reduced delivery times by 30%, providing customers with a high level of reliability assurance.
“2026 is a pivotal year for the company’s ‘technology-driven + market-depth’ strategy. We will continue to ramp up R&D investment, focusing on cutting-edge fields such as new-energy vehicles and intelligent driving, and build a sealing technology ecosystem with global competitiveness.”
According to industry forecasts, as the penetration rate of new-energy vehicles exceeds 50%, the automotive sealing components market will maintain an average annual growth rate of 12%. The company is gradually expanding into emerging markets such as Southeast Asia.
