OverviewFoam sealing material with closed cell structure offering flexibility and elasticity as well as weather resistance and watertightness.
Product descriptionNo.6800 Series are high-function foam sealing materials composed of EPDM rubber foam with a closed cell structure, providing superior durability and weather resistance among general-purpose rubbers. The series includes tape products coated with butyl adhesive (EM-142) and synthetic resin adhesive (No.681); choose the type that matches your application requirements.
Features- Superior weather resistance and watertightness; better heat resistance than foam water sealers such as urethane and polyethylene.
- EM-142 is coated with butyl rubber adhesive for good adhesion to rough surfaces.
- No.681 is coated with synthetic resin adhesive offering strong holding power, heat resistance and weather resistance.
- Closed cell structure delivers excellent flexibility and elasticity.
- Easy installation in clearances with complex shapes.
StructureClosed-cell EPDM rubber foam structure designed for sealing applications.
