Eco Seal® Series

ESL600 & ESL1000


Eco Seal® Series foams (ESL), are specially formulated for more demanding industrial, automotive, and construction applications. Characteristics common to all Gaska Tape flexible closed-cell foam products include the ability to make a long life seal against air, moisture, light and dust penetration when compressed 30% or more.

ESL600, light density foam is easily flexed and compressed and exhibits excellent conformability.  Test results demonstrate that ESL600 can be classified to 2C0 (SCE-40) as specified by ASTM D 1056 and SAE J18.

ESL1000 is a medium density foam that exhibits good conformability with excellent dimensional stability.  Test results demonstrate that ESL1000 can be classified to 2C1 (SCE-41) as specified by ASTM D 1056 and SAE J18.


  • Revolutionary in composition, Eco Seal® Series foam products compete favorably with high end rubbers such as EPDM, Nitrile, SBR Blends, ECH, EPT.
