DOW AUTOMOTIVE: Structural Foam Inserts
Dow Automotive has pioneered an innovative technology in the development of structural foam inserts (SFIs) to support vehicle body stiffness and handling performance attributes on a range of vehicle types. BETAFOAM structural polyurethane foam is molded into pre-formed geometries and, when cured, is overmolded with BETAMATE structural adhesive using a Dow Automotive proprietary resin transfer molding process. The SFIs nest seamlessly into sheet metal cavities, and the epoxy adhesive expands and bonds the foam parts to the surrounding steel structure during plant bake processes. SFIs from Dow Automotive are currently in use on several GM vehicles, including in the upper-center-pillar area of the 2005 Buick LaCrosse.
