Foamcore, foam board, or paper-faced foam board is a lightweight and easily cut material used for mounting of photographic prints, as backing for picture framing, for making scale models, and in painting. It consists of a board of polystyrene foam clad with an outer facing of paper on either side, typically white clay-coated paper or brown ...
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 ...
Common uses. Closed-cell PVC foamboard is mainly used for industrial and manufacturing purposes. The material is primarily used in the manufacturing of signs and displays which are used for promotion ads, as well as road signs. [6] Its appealing material properties have made it popular among the makers of scale models and theatrical props.
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 foams, the gas ...
Structural insulated panel. SIPs are most commonly made of OSB panels sandwiched around a foam core made of polystyrene. A structural insulated panel, or structural insulating panel, (SIP), is a form of sandwich panel used in the construction industry. SIP is a sandwich structured composite, consisting of an insulating layer of rigid core ...

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.
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 equipment, packaging, footwear ...
