Core Molding Technologies, Inc. (NYSE MKT:CMT), a leading North American compounder of custom sheet molding compound (SMC) and molder of fiberglass reinforced thermoset and thermoplastic compounds, today announced a breakthrough ultra-low density SMC formulation and an addition to Core’s industry-leading suite of low-density composite product offerings.

Core’s new, ultra-low density Hydrilite ™ SMC has a nominal density of 0.98 while exhibiting mid-range mechanical performance and a high-quality surface appearance. The achievement places the SMC system below the density of water and below most thermoplastic systems. The breakthrough represents a nearly 50% reduction from standard-density SMC materials and a 17% reduction from Core’s industry-leading lightweighting material solutions that include the commercially-successful Airilite® and Econolite® SMC systems that test at 1.18

“Across our markets, customers continue to challenge us to lower the density of fiberglass reinforced material systems to support their lightweighting efforts,” said Terry O’Donovan, vice president, marketing and sales for Core Molding Technologies. “A density of 1.0, equivalent to the density of water, has long been seen as a practical limit by formulation chemists throughout the thermoset industry,” O’Donovan added. “To be the first to crack that barrier and achieve a functional system at 0.98 is a high achievement for our development team and a meaningful product advance for our customers.”

Hydrilite™ SMC is formulated with a high-performance resin system and is reinforced with 41% glass fiber by weight. “The use of glass fiber results in a material system considerably more economical than those based on carbon fiber, while achieving even lower density,” O’Donovan said. Hydrilite™ SMC achieves nominal tensile strength of more than 75 MPa and impact strength of 850 J/m. Both results are on par with Core’s standard-density reinforcement-grade SMC formulations. This performance, along with other mechanical properties of the system, make it ideal for a broad range of lightweighting applications requiring a combination of strength and high appearance. A commercial program using Hydrilite™ SMC is undergoing customer qualification, and other applications are in development.

“Hydrilite™ SMC is a significant advance in lightweighting performance,” O’Donovan said. “A molded product that weighs 100 pounds in standard-technology SMC, would weigh only 51 pounds in Hydrilite™ SMC. Yet, Hydrilite™ is probably not the stopping point. We are currently working to develop a full Class A version of the product, while retaining the 0.98 density and adequate mechanical performance. With an ongoing need for lightweighting solutions, no doubt our customers will continue to request further reductions in density, which we will strive to achieve,” O’Donovan stated.

Evaluation plaques and material performance data for Hydrilite™ SMC are available to qualified customers.
