Syntactic foam

Advantic is a syntactic foam made by mixing or combining hollow glass microspheres with an epoxy resin. This high-strength composite solves many of the problems associated with other common tooling materials. Cornerstone Research Group (CRG) Industries’ proprietary mixing process minimizes the number of microspheres that break during mixing, a common problem in manufacturing syntactic materials. This process enables Advantic to maintain low density with high uniformity and minimum void content.

Because Advantic is lightweight, it reduces wear and tear on machining equipment. It also has low thermal conductivity and specific heat, so it requires little warm-up time and virtually eliminates plug sticking during thermoforming. Advantic is dimensionally stable and will keep its shape over a wide range of temperatures. The material can also be machined using standard carbide-tipped tools in sheet-fed, rotary, or in-line machines for a variety of applications.

Advantic is available in small or large lots of customized material with custom properties. CRG Industries can customize properties such as compressive strength, flexure strength, material density, operational temperature, chemical resistance, electrical properties, thermoconductivity, water absorption, and surface finish.
