SynFoam syntactic Foam Logo

SynFoam LG is a unique, expandable, closed cell syntactic foam that provides very low density and moderate strength. SynFoam LG is an ideal replacement for polyurethane foams where higher modulus is needed to support lightweight structures. It is suitable for numerous marine and aerospace applications or where machining of parts is either impractical or too expensive.

SynFoam LG is available as cubic foot kits. Each kit contains an A and B side that must be mixed together prior to casting. Cure is achieved within 24 hours and full properties will be realized after 7 days at room temperature. Densities can be customized to the user's specifications. Interlayer adhesion allowing large structures to be made with multiple pours.

If you have a specific mold for use with SynFoam LG we also provide final casting and fabrication services. Services include casting and finishing with a quality marine based paint.
