Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...
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.
Foam rubber (also known as cellular rubber, sponge rubber, or expanded rubber) is rubber that has been made with a foaming agent so that its structure is an air-filled matrix. Commercial foam rubber is generally made of synthetic rubber, natural latex, or polyurethane. Latex foam rubber, used in mattresses, is well known for its endurance.
Robert A. Volz is credited with discovering the first process for making reticulated polyurethane foam in 1956 while working for the Scott Paper Company. [6] Production of reticulated polyurethane foam is a two-step process that begins with the creation of conventional (closed-cell) polyurethane foam, after which cell faces (or "windows") are removed.

Polyisocyanurate Typically R-5.6 (RSI-0.99) [8] or slightly better after stabilization – higher values (at least R-7, or RSI-1.23) in stabilized boards. [9] Less flammable than polyurethane. Phenolic injection foam Such as Tripolymer R-5.1 per inch (ASTM-C-177).
Solid polymeric foam for packaging under the optical microscope. A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1]Examples include:
Foam structures Several types of polymeric foams are used for cushioning, the most common being expanded polystyrene, polypropylene, polyethylene, and polyurethane. These can be molded engineered shapes or sheets which are cut and glued into cushion structures. [5] Convoluted (or finger) foams are sometimes used. [6]
