Thermoset sheet molding compounds (SMC) are comprised of fiber reinforcement in a polymer resin. Once molded, the materials are exceptionally strong, able to absorb both shock and vibration. They are also resistant to a variety of corrosive and natural forces, such as UV light and moisture, and maintain their shape and performance attributes for decades. Components can be molded in color, or color can be applied after molding.

IDI materials offer superior moldability and parts consolidation, which allows manufacturers to design the most efficient and cost-effective solution for their market. Aeroform thermoset materials also comply with various safety regulations and fire codes, increasing the potential number of installations.
