EPT-Sealer No.686T

EPT-Sealer No.686T is a semi-closed cell EPDM foam laminated with a baseless adhesive tape with excellent sealing properties.

The semi-closed cell structure of EPT-Sealer No.686T combines the flexibility of open cell types with the excellent sealing capabilities of closed cell types (after compression). This unique foam is laminated with a baseless adhesive tape to seal (complex) gaps against water, wind, dust, noise and heat.
