EPT-Sealer 686T

General description

EPT-Sealer 686T is a semi-closed cell EPDM foam with excellent sealing properties. The semiclosed cell structure combines the flexibility of open cell types with the excellent sealing capabilities of closed cell types (after compression). This unique foam can be laminated with Nitto’s advanced adhesive technology to seal (complex) gaps against water, wind, dust, noise and heat.

Features

  • semi-closed cell structure
  • super soft / conformable
  • low compression load
  • ozone resistance
  • good weatherability
  • fungus free
  • excellent ageing performance
  • good water sealing
  • excellent sound insulation
  • wide range of performing tapes
