SynFoam syntactic Foam Logo

SynFoam ELG is a two part closed cell syntactic resin system that is based on epoxy rather than polyurethane chemistry. ELG can withstand continuous exposure up to 300oF and retain it's rigidity. SynFoam ELG has low dielectric loss and dielectric properties. The weight is significantly lower than most low loss materials used for electronic applications. The system is suitable for both electronic potting and encapsulation as well as structural support. SynFoam ELG is shipped as two components which when mixed together can be poured and cast into various shapes and sizes.

SynFoam ELG is available in quart, 1 and 5 gallon kit sizes. Each kit contains an A and B side that must be mixed together prior to casting. SynFoam ELG 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 ELG.
