Recent developments have shown that polyurethane structural foam materials work well in exterior trim applications. In the past, these materials had been considered mainly for interior applications. However, new designs in spoilers have shown that they are also an excellent choice for exterior trim components as well. In reviewing these spoiler programs, physical properties, processing, and design advantages will be discussed. By using the polyurethane structural foam process, spoilers can be molded which are single components, are light-weight, and have good physical properties. These materials also require less postfinishing and can be painted with conventional paints.
