Description: VOLARA 4EO is a general purpose cross-linked polyethylene foam (XLPE) with an EVA copolymer which combines low cost with a wide range of material properties. 4EO is stronger and softer than the 4A grade, making it better suited to medical and food grade applications. As a closed cell foam, VOLARA 4EO can be used in many gasketing applications to seal against dust, air and water. Cross linked polyethylene (XLPE) is resistant to a wide range of chemicals and VOLARA 4EO closed cell foam has low water absorption. VOLARA has a smooth skin, making it popular in specialty packaging and is commonly used as the foam in foam backed adhesive tapes. This XLPE sponge is often used as flooring underlay, window glazing and electrical outlet insulation. Cross-linked polyethylene foam is a common material in the HVAC and lighting industries. If more tensile or tear strength is required, VOLARA’s 6 # density might be an alternative. VOLARA 2A and 4A can be used when strength is not an issue, but thickness and economy is. 2AF is used when a UL 94 HF-1 rating is required.
VOLARA is available in many styles and thicknesses. The most common are 2A and 2AF (fire rated), 4A, and 6A. The EO grades are suited to medical and food applications, but typically require large minimums. Generally VOLARA densities go up as thickness goes down: 2# density (2A and 2AF) is common in 1/8" thickness, 4# density (4A and 4EO) in 1/16th and 6# density (6A and 6EO) in 1/32" thicknesses.
VOLARA is easily fabricated. VOLARA can be die cut by many methods, including high speed rotary kiss cutting. It can be laminated to different adhesives, such as rubber and acrylic based pressure sensitive adhesives. VOLARA 4EO can be provided in full rolls up to 60" wide, or slit rolls as narrow as ¼", in thicknesses from .031" to .50" (thinner gauges require higher densities). We can die cut or waterjet cut parts to your exact specifications
