SynFoam® EFC-50

SynFoam EFC is a two part closed cell syntactic resin system that is based on epoxy rather than polyurethane chemistry. SynFoam EFC provides far greater strength, stiffness, impact absorption, and shear properties than standard core materials. SynFoam EFC will not absorb resins or other materials making it a good selection for use in RTM, vacuum bag, pultrusion or other composite applications. SynFoam EFC has good resistance to heat and is resistant to water, hydrocarbon fuels, and chemicals. It has excellent adhesion to metals and can be used as a gap filler or to promote metal to composite bonding. SynFoam EFC is shipped as two components which when mixed together can be poured and cast into various shapes and sizes. SynFoam EFC is available in 1 and 5 gallon kit sizes. Each kit contains an A and B side that must be mixed together prior to casting. The B side selection is dependent on the final use temperature for the material. EFC can maintain its rigidity between 100 and 150oC depending on the selected curative. SynFoam EFC does not require temperature to cure, but requires higher postcure temperatures to reach the maximum service use temperature. Please consult the appropriate instructions prior to using EFC. SynFoam provides custom fabrication of parts and can cast SynFoam EFC to size.
