During the driving process of a car, the car body is constantly subjected to various external forces such as road bumps, vibrations, and accidental collisions. TPE material has excellent flexibility and elastic recovery ability, which can effectively absorb and disperse these impact forces. This makes automotive corner connectors less likely to crack or deform when subjected to external forces, thereby providing reliable connection and buffer protection for the car body structure and significantly improving the overall safety and durability of the car.
Cars will be exposed to various harsh climatic conditions and complex chemical environments during their service life, such as high-temperature exposure, severe cold freezing, rain erosion, and pollution from various chemical substances on the road. TPE automotive corner connectors have excellent weather resistance and chemical stability. During long-term use, they can maintain the stability of their physical properties and appearance color without aging, embrittlement, discoloration, or corrosion by chemical substances.
With the increasing global requirements for energy conservation and emission reduction in automobiles, lightweighting of automobiles has become an important trend in the industry. Compared with traditional metal corner connectors, TPE materials have obvious density advantages and can effectively reduce the weight of the vehicle body. This not only helps to reduce the fuel consumption and exhaust emissions of automobiles, which is in line with the concept of environmental protection, but also can improve the handling performance and acceleration performance of automobiles, bringing drivers a more flexible and comfortable driving experience.
TPE material has good molding processing performance and can easily realize the production and manufacturing of complex-shaped automotive corner connectors through various process methods such as injection molding and extrusion. Its melt has good fluidity and can quickly fill the mold cavity. The molding cycle is short and the production efficiency is high. At the same time, TPE materials can also be co-extruded or two-color injection molded with other materials (such as plastics, rubber, etc.) to achieve diversified design functions and appearance effects and meet the personalized design needs of automakers for corner connectors of different models and different parts.
The TPE corner joint material products developed by Shandong Tairuifeng are benchmarked against Company J in Japan and Company A in Germany. They are mainly used in door seals, weather strips, and front and rear window guide grooves. They can be connected to foamed EPDM/attached sliding material EPDM/flocked EPDM/dense EPDM, etc. They have the advantages of excellent corner joint tensile force after thermal aging, not easy to shrink, not easy to crack, low odor, excellent adhesive strength tensile value, strong aging resistance, and high cost performance.
