What Is High Density Polyurethane Foam

Spray polyurethane foam residential insulation.

What is high density polyurethane foam.

Foam densities range from approximately 2 to 60 lbs. High density urethane foam board also known as hdu board is used for hand carved signs as well as cnc machining. We have the ability to align hdu foam properties with your specific needs and help you contain material and manufacturing costs. Polyurethane foam is a blanket term that includes any foam that is synthesized using polyol and diisocyanate.

High density foam is a type of polyurethane foam that is composed of a large amount of open cells or bubbles that are packed tightly together. Precision board high density urethane pblt from coastal enterprises is a closed cell rigid polyurethane product made specifically for applications of up to 200 f continuous exposure pblt high density urethane is available in a wide range of standard sheet sizes and standard densities and can be cut or bonded into a variety of shapes for final machining or shaping. Pu foam density considerations. The result of this higher concentration or density is that air is able to pass through the holes in the cells with greater ease making it much easier to provide comfortable padding for cushions mattresses and other similar products.

The ratio of polyol to diisocyanate is 2 1 to form polyurethane though there may be other compounds that are added to create just the right amount of density for each piece of foam. Our high density flame retardant rigid polyurethane foams are also available in sheets and blocks or molded. Precision board plus high density urethane pblt is a closed cell rigid polyurethane product made. Unlike thermoplastic foams pvc san the unit cost of polyurethane foam increases in a linear fashion with density so a 20 lbs per cubic foot polyurethane foam will be.

These include but are not limited to. We recommend this type of foam because it s exceptionally durable and long lasting with properties that allow it to be employed in any heavy use environment. High density foam is a polymer created during a chemical reaction between polyol and diisocyanate two chemicals created from organic compounds. Raku tool styling board sb has a fine surface structure and lends itself to both manual and mechanical processing.

In the early 1990s because of their impact on ozone depletion the montreal protocol restricted the use of many chlorine containing blowing agents such as trichlorofluoromethane cfc 11. High density polyurethane foam. Polyurethane foam including foam rubber is sometimes made using small amounts of blowing agents to give less dense foam better cushioning energy absorption or thermal insulation.
