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.
This is important if space is limited, because it allows a thinner layer of insulation to be used. For example, a 1-inch layer of closed-cell foam provides about the same insulation factor as 2 inches of open-cell foam. Closed-cell foam is very strong, and structurally reinforces the insulated surface.

Is the key component of a line of inflatable spacecraft developed by Bigelow Aerospace: Viton: Poly(vinylidene fluoride-co-hexafluoropropylene) Elastomer: Depends on the grade of the polymer. Viton B is used in chemical process plants and gaskets. Zylon: poly-p-phenylene-2,6-benzobisoxazole (PBO) Very high tensile strength and thermal stability
Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...
Typically, high-resiliency, high-density plastic foam with a thin plastic film is used to keep out water that might get by the seams. Closed-cell foam is often used for smaller cushions, which can sometimes double as flotation devices.
