EPT-Sealer No.686

EPT-Sealer No.686 is a semi-closed cell EPDM foam laminated with an acrylic-based double-coated adhesive tape for excellent sealing properties.

The semi-closed cell structure of EPT-Sealer No.686 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 acrylic-based double-coated adhesive tape to seal (complex) gaps against water, wind, dust, noise and heat.
