Core Molding Technologies Inc. (Columbus, Ohio, USA), a North American compounder of custom sheet molding compound (SMC), has developed a low-density SMC with high surface quality and improved economics over previous low-density materials offered by the company. The Featherlite brand of SMC has a nominal density 25 percent less than the density of industry-standard SMC formulations. The material offers good toughness and is said to be ideal for high-impact applications where the strength of a glass-reinforced composite is also required. Because the material achieves lower density without the use of glass microspheres, it reportedly reduces the risk of “paint pops” in Class A applications and offers high surface quality not typical of SMC products in this density range.
