Closed Cell Polyethylene Foam Insulation
The benefits of polyethylene foam include.
Closed cell polyethylene foam insulation. Tundra closed cell polyethylene foam semi slit pipe insulation is used in residential and light commercial plumbing projects to prevent heat loss and protect pipes from freezing. Impact and vibration absorption. It is very buoyant and is frequently found in flotation devices and other nautical equipment. It is used as thermal insulation as shock absorption to dampen sound and as cushioning.
Pe foam is closed cell foam made from polyethylene and blended copolymers. Closed cell spray foam insulation is an air barrier water resistive and a vapor barrier. Closed cell is a two component medium density one to one by volume spray applied polyurethane foam. Strong and resilient polyethylene foam is often sold as closed cell foam sheets.
It is available in wall thicknesses of 3 8 to 1 in sizes ranging from 3 8 up to 4 ips id. It has a high level of chemical cross linking. Polyethylene foam rolls or sheets can be used for insulation. To produce closed cell requires the use of an a component iso and a blended b component resin which contains zero ozone depleting blowing agents catalysts polyols and fire retarding materials.
Polyethylene closed cell foam is available in sheets cylinders and tubes that are great for expansion joint filler backer rod insulation buoyancy components and packaging. Polyethylene sheeting is also easily laminated together to create thicker sections that can then be cut for furniture inserts personal flotation device inserts or specialized packaging. The result is a smooth fine cell foam sheet suitable for many situations.
