Abstract: A structural foam and a structural adhesive produced by Henkel Co. were introduced contributing to light weight
construction and automotive safety for new energy automotive industry. Of these two new solutions, the chemical aspects,
mechanical properties were measured for automotive application cases and the improvement contributions to vehicle
performance. The results show that the structural foam has the excellent properties of being lightweight, providing both high
strength and stiffness, therefore, offering many weight saving and cost reduction solutions, thus, increases the energy absorption
capacity of the vehicle structure during collision situations; the structural adhesive provides an effective joint line, optimizing
stress distribution, increasing structural strength and stiffness, preventing galvanic corrosion, and hence can also provide
alternative cost reduction opportunities. These technologies were used by many OEMs (Original Equipment Manufacturer) on
automotive production lines.
