A memory foam mattress is usually denser than other foam mattresses, making it both more supportive and heavier. 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
Flexible polyurethane foam. The so-called flexible polyurethane foam (FPF) is produced from the reaction of polyols and isocyanates, a process pioneered in 1937. [1] FPF allows for some compression and resilience that provides a cushioning effect. Because of this property, it is often used in furniture, bedding, automotive seating, athletic ...
Polyurethane synthesis, wherein the urethane groups −NH− (C=O)−O− link the molecular units. A kitchen sponge made of polyurethane foam. Polyurethane (/ ˌpɒliˈjʊərəˌθeɪn, - jʊəˈrɛθeɪn /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links.
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 ...
Foam glass is a kind of lightweight, high-strength building material and decorative material with excellent performance (insulation) and sound absorption that is both moisture-proof and fireproof. The temperature range is from -196 degrees to 450 degrees Celsius. Although other new insulation materials emerge in an endless stream, foam glass ...
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.
The generalised chemical structure of polyisocyanurate showing the isocyanurate group. The polyols are abbreviated as R-groups.. Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
Cleaning sponge. Foams are two-phase material systems where a gas is disbursed in a second, non-gaseous material, specifically, in which gas cells are enclosed by a distinct liquid or solid material. [1]: 6 [2]: 4 [3] The foam "may contain more or less liquid [or solid] according to circumstances", [1]: 6 although in the case of gas-liquid ...
