Specialities HIGH DENSITY.
Rigid polyurethane PUR foam blocks and sheets free of CFC and HCFC gas types with densities of between 130 and 450 kg/m 3 easy to machine via milling or water-jet cutting. These products like traditional polyurethane foams have a good thermal insulation coefficient and a high mechanical resistance. They are lightweight and easy to machine paint and cover with mastic or polyester. High density rigid polyurethane PUR foam blocks. Height of the block according to the density. HD-1 HD-2 HD-3 HD-4.

Foam rubber Wikipedia.
The largest amount of polyurethane is used by these industries construction transportation home furniture noise and vibration reduction and carpet. Construction uses 27% of polyurethane and transportation uses 21%. Flexible foam is the leading material usage at 44% total volume and rigid foam material at 28% of the United States market. Rates of polymerization can range from many minutes to just a few seconds. Fast reacting polymers feature short cycle periods and require the use of machinery to thoroughly mix the reacting agents. Slow polymers may be mixed by hand but require long periods on mixing as a result industrial application tends to use machinery to mix products.
High Resilience Foams Bergad Specialty Foams Composites.
Tell us about your project. High Resilience foam or HR foam is open-cell flexible polyurethane foam that has a less uniform more random cell structure that helps add support comfort and resilience or bounce. HR foams have a high support factor and greater surface resilience than Viscoelastic foams. Unlike Viscoelastic foam HR foam has a very fast recovery and bounces back to its original shape immediately after compression. While HR foams are a significantly smaller part of what Bergad offers we do offer foams in a wide range of physical characteristics with. Densities from 2 to over 30 pounds per cubic foot.
High-density and Eco-friendly Polyurethane Foams from General Plastics Manufacturing.
In the latter case two reactive components are combined and poured into an open mold which is then closed and the mixture is allowed to expand and cure. Foam densities range from about 3 to 50 pounds/cubic foot. Depending on the foam production process foams of the same density can differ in strength. Different manufacturing techniques demand different foam curing temperatures and chemical formulations. Integral-skin foams from General Plastics enable items like aircraft armrest padding to be easily removed from the mold in the precise shape needed or airbrushed in the preferred color. Properties and Applications of Polyurethane Foams. General Plastics polyurethane foams are smooth uniform and grain-free cell structures that support very fine surface finishes.
