What is Urethane Foam?
Urethane foam is an artificial material with several different uses. The manufacturing process can produce foams of varying densities and flexibilities. This means it can serve functions as diverse as bedding, packaging and footwear. It is important to note that urethane foam is most commonly used to refer to a material made from polyurethane. The urethane reference in this name is to the type of links, also known as carbamates, which join the units in polyurethane. There is some potential for confusion as the word urethane on its own is often used for a specific carbamate also titled ethyl carbamate. Despite the name, this substance does not appear in urethane foam. Perhaps the best known use of urethane foam is in bedding such as mattresses. Because it is artificially made, this foam can be made to a particular density, meaning manufacturers can offer a range of mattresses with different degrees of softness or firmness and even produce a mattress to order. Urethane foam itself does n
Our urethane foam is a two part, pour in place liquid that when combined will expand into a rigid, closed cell polyurethane foam. 2. What are the differences between the foam densities? The densities of the foam refer to the weight of the foam when cured per cubic foot (12″ x 12″ x 12″). Higher densities will result in a heavier foam which is also stronger. We have listed brief examples of hardness and physical properties to help you select the correct density here. Please also be aware that as you increase in density your expansion ratio will decrease, resulting in a higher cost per cubic foot of cured foam. 3. Which density is used for flotation in the bottom of a boat? Our 2LB foam is generally used for most marine flotation requirements due to its good flotation properties of approx. 60 lbs of buoyancy per cubic foot. For flotation applications requiring some structural elements such as helping to support your deck or strengthening between stringers or bulkheads we would recommend
