An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.
Memory foam mattresses are often sold for higher prices than traditional mattresses. Memory foam used in mattresses is commonly manufactured in densities ranging from less than 24kg/m 3 (1.5 lb/ft 3) to 128kg/m 3 (8 lb/ft 3) density. Most standard memory foam has a density of 16–80 kg/m 3 (1 to 5 lb/ft 3).
Low-density polyethylene (LDPE) foam, first grade of polyethylene (PE) Nitrile rubber (NBR) foam, the copolymers of acrylonitrile (ACN) and butadiene; Polychloroprene foam or Neoprene; Polyimide foam; Polypropylene (PP) foam, including expanded polypropylene (EPP) and polypropylene paper (PPP) Polystyrene#Foams (PS) foam Expanded polystyrene (EPS)
This is a list of insulation materials used around the world.. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value.
This is a new generation eco-friendly foam blowing agent that is free of Chlorofluorocarbons (CFCs), Hydrochlorofluorocarbons (HCFCs), and Hydrofluorocarbons (HFCs) based on naturally occurring methyl methanoate. Open-cell (low density) polyurethane White or yellow. Expands to fill and seal cavity, but expands slowly, preventing damage to the wall.
High density foam Similar to memory foam mattresses, a high density foam mattress uses a more compact foam typically made from polyurethane. This kind of foam is made largely from open cells that are packed together tightly. [24] High density foam mattresses offer comfort and longevity because they are more dense than a traditional foam mattress.

Spray polyurethane foam (SPF) insulation can be categorized into two different types: light-density open-cell spray foam insulation and medium-density closed-cell spray foam insulation. Both types of SPF are thermoset cellular plastics comprising millions of small cells. [8] Open cell spray polyurethane foam insulation being applied in wall ...
