SynFoam LFR is a two part, flame retardant closed cell syntactic resin system that is based on epoxy rather than polyurethane chemistry.
SynFoam LFR provides far greater strength, stiffness, impact absorption, and shear properties than standard
core materials. LFR is similar to our other materials except it adds a higher level of flame retardancy for applictaions where a flame retardant
material is needed. SynFoam LFR will not absorb resins or other materials making it a good selection for use in RTM, vacuum bag, pultrusion or other composite applications.
SynFoam LFR 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 LFR is shipped as two components which when mixed together can be poured and cast into various shapes and sizes.
SynFoam LFR 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. LFR can maintain its rigidity between 100 and 150oC depending on the
selected curative. SynFoam LFR 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 LFR.
SynFoam provides custom fabrication of parts and can cast SynFoam LFR to size. Please contact us for more information on fabrication services.
