The Technology Research and Development Department has achieved another significant breakthrough in the field of core connecting components for chassis and suspension systems, successfully developing and validating a new-generation high-performance bushing assembly. As the “silent joint” that plays a crucial role in vehicle dynamics and ride comfort, this upgrade addresses the fundamental connection points, markedly enhancing the vehicle’s vibration isolation performance, handling precision, and noise reduction levels.
Material Knowledge in Rubber Products

The commonly used natural rubbers for conveyor belts include: National Standard No. 1, National Standard No. 2, and Imported Grade 3.
Performance characteristics: NR exhibits high elasticity at room temperature, but gradually softens upon heating. It begins to flow at 130–140°C and becomes a highly viscous fluid above 150–160°C. Decomposition starts at 200°C and accelerates rapidly at 270°C. At -70 to -72°C, however, it turns brittle and reverts to its normal state after baking.

Dalian Bohai Rubber & Plastic Co., Ltd. is a rubber products enterprise integrating R&D, production, and sales. We specialize in the customization and production of compounded rubber (also known as “rubber compounds”). Based on different customer requirements, we use raw rubber combined with compounding agents and additives, processed through a closed-milling system to create semi-finished materials that can be directly used for vulcanization and molding. These materials find extensive applications in industries such as automotive manufacturing (sealing strips, vibration-damping pads, fuel hoses) and mechanical engineering (conveyor belts, sealing rings, cushioning components).

Currently, the rubber industry is facing multiple challenges, including volatile raw material prices, increasingly stringent environmental regulations, intensifying homogeneous competition, and rising demands for more sophisticated quality control. How to simultaneously achieve improvements in product quality, cost reduction, efficiency enhancement, and green transformation has become the key to breaking through these industry bottlenecks. In recent years, an increasing number of rubber enterprises have proactively adopted the PDCA cycle management model (Plan, Do, Check, Act), deeply integrating it into the entire value chain—from R&D and production to quality control and equipment maintenance—thereby overcoming challenges through “closed-loop management and spiral improvement.”
Visit SAIC Volkswagen R&D Center and Procurement Center on January 22nd

Firstly, we had a technical exchange with SAIC Volkswagen R&D Center on the sealing of body sheet metal holes. At present, with the rapid development of new energy vehicles, how to ensure passenger safety in the event of battery thermal runaway is a key development direction for major automakers. There is an urgent need for sheet metal hole seals under high temperature conditions. Dalian Bohai Rubber has many years of experience in developing rubber seals with temperature levels below 200 ℃, which can meet the sealing and flame retardant requirements of host factories at this temperature. SAIC Volkswagen stated that in the future, supplier recommendations can be made to jointly develop new material products to meet the increasing safety requirements.
