Description: VOLARA 4A is a general purpose cross-linked polyethylene foam (XLPE) which combines low cost with a wide range of material properties. As a closed cell foam, VOLARA 4A 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 4A 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 tape. This XLPE material 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. VOLARA 4A has a Thermal Conductivity of .30, making it good insulation and has a service temperature of -40° F to +160° F. If more tensile or tear strength are required, VOLARA’s 6 # density (6A and 6EO) might be an alternative. VOLARA 4A meets the Federal FMVSS-302 burn rating, if the UL 94 HF-1 fire rating is required, 2AF should be used.
VOLARA is available in many styles and thicknesses. The most common are 2A, 2AF, 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) in 1/16th and 6# density (6A) 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 4A can be provided in full rolls up to 60” wide, or slit rolls as narrow as ¼", in thicknesses from .062" to .50" (thinner gauges require higher densities). We can die cut or waterjet cut parts to your exact specifications.
