Phyzite 380- Expansion Joints

Phyzite 380™- Expansion Joints

Phyzite 380™is a pre-formed, closed cell, low-density, cross-linked EVA/PE (Ethyl Vinyl Acetate-Polyethylene) foam joint seal. The material is typically used as an expansion joint seal or as a gasket material in bridge decks, commercial building, parking decks, water treatment facilities and other industrial applications. Phyzite 380™ contains a Hindered Amine Light Stabilizer (UV inhibitor) which provides increased performance when exposed to UV light that other foam products containing carbon black. When installed within the CEVA® Joint Systems, the material acts as a water tight seismic expansion joint seal. Additional features include applications in hydrostatic environments. Phyzite 380™can be installed in ponding/standing water and is safe for use in potable and processed water applications. Phyzite 380™ meets ADA criteria for ground and floor surfaces as stated in the rules and regulations section of the Federal Register Volume 58 no. 144, US Access Board.
