EPT SEALER No.685 Series

Foam sealing material with semi-closed cell structure offers flexibility and elasticity as well as weather resistance and water tightness.

Semi-closed cell structure

Outline

No.685 Series are high-function foam sealing materials consisting of EPDM rubber foam with semi-closed cell structure offering the best durability and weather resistance of all general purpose rubber. Because they are made of flexible material, these products offer superior watertightness and airtightness. No.685 Series includes tape materials coated with rubber adhesive and acrylic adhesive. You can select the type that best meets your needs. In addition to black, the series now includes gray and white color variations.

Features

• Offers superior durability and resistance to weather, cold and heat (-20°C to 100°C), and chemicals (acids and alkalis).
• Compression load (stress) is slight, so structure is not deformed after foam filling.
• Flexible material is easy to use when compressed.
• Low specific gravity of 0.095; foam pieces do not fuse together.
