What is the density of polyurethane foam?
PU FOAM DENSITY CONSIDERATIONS Foam densities range from approximately 2 to 60 lbs. per cubic foot (48 to 961 kg/m3). 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 PU foam will be approximate twice the cost of a 10-lb.
What is the density of spray foam?
Open-cell spray polyurethane foam, sometimes called half-pound foam, has a typical density of 0.5 lb. per cubic foot and a typical R-value of 3.5 or 3.6 per inch. Closed-cell foam, sometimes called two-pound foam, has a typical density of 2 lbs. per cubic foot and an R-value of 6 to 6.5 per inch.
What is the density of structural foam?
0.7 g/cm3
Structural foam 0.7 g/cm3. Apparent density.
Which spray foam has the highest density?
High-density spray foam insulation has the densest structure of all spray foam insulation types. Due to its high density, more material is needed to cover and insulate an area. For each cubic foot of high-density spray foam insulation, roughly 3 lbs. of closed-cell foam is used.
What is the most dense spray foam?
Versi-Foam® is available in a higher density system, with a free rise density of 2.8 pounds per cubic foot, 3 pounds per cubic foot in place. It is 98% closed cell resulting in an R-factor of 7.7, a low moisture absorption rate and excellent compressive strength.
What is foam density rating?
Foam density is a unit of measurement that dictates how many pounds polyurethane foam can support per cubic foot. In short, foam density tells you the strength of the foam, and that decimal you’re seeing is the number of pounds each cubic foot can hold.
What is high density spray foam?
What is the densest foam you can buy?
Many conventional foams have a density between 1LB and 3LB. However, the densest materials can be as much as 10 or 15LB. High-density foam, Like The Foam Factory’s 2.8LB density HD36-HQ foam, is optimal for uses that receive heavy or daily use like couch cushions, bedding, or automobile seating.
