Typical Properties of 6A Volara
Description: VOLARA 6A 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 6A 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 6A 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 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 and has a service temperature of -40° F to +160° F. VOLARA’s 6 # density (6A) is used in applications where greater tear strength and tensile strength are needed. 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, 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 6A 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.
