Polyurethane
Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, ther...
List of polyurethane applications
Polyurethane products have many uses. Over three quarters of the global consumption of polyurethane products is in the form of foams, with flexible and rigid types being roughly equal in market size. ...
Polyurethane varnish
Varnish is a transparent, hard, protective finish or film primarily used in wood finishing but also for other materials. Varnish is traditionally a combination of a drying oil, a resin, and a thinner ...
Polyurea
Polyurea is a type of elastomer that is derived from the reaction product of an isocyanate component and a synthetic resin blend component through step-growth polymerization. The isocyanate can be aro...
Polyaspartic
Polyaspartic chemistry was first introduced in the early 1990s making it a relatively new class of coating. Polyaspartic is actually an aliphatic polyurea because it is derived from the reaction prod...
Prepolymer
The term pre-polymer refers to a monomer or system of monomers that have been reacted to an intermediate molecular mass state. This material is capable of further polymerization by reactive groups to ...
Reticulated foam
Reticulated foam is a very porous, low density solid foam. 'Reticulated' means like a net. Reticulated foams are extremely open foams i.e. there are few, if any, intact bubbles or cell windows. In con...
Coelan Marine Coatings
Coelan Marine Coatings area special highly UV-resistant coatings invented by Coelan in 1992 and are used widely in the marine industry as coatings for wood, plastic, metal and fiberglass surfaces. Co...
LRPu
LRPu or low-resilience polyurethane is a material distinguished by an "ability to slowly return to its original shape" (viscosity).The resulting impact resistance results in LRPu being used in soft la...
Shellac
Shellac is a resin secreted by the female lac bug, on trees in the forests of India and Thailand. It is processed and sold as dry flakes (pictured at right) and dissolved in ethanol to make liquid she...
Polyisocyanurate
Polyisocyanurate, also referred to as PIR, polyiso, or ISO, is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. Its chemistry is similar to polyurethane (PUR) exc...
Moisture cure polyurethane
Moisture-cure polyurethanes or polyurethane prepolymer are isocyanate-terminated prepolymers that are formulated to cure with ambient water. Cured PURs are segmented copolymer polyurethane-ureas exhi...
Lacquer
Lacquer is a clear or coloured wood finish that dries by solvent evaporation or a curing process that produces a hard, durable finish. This finish can be of any sheen level from ultra matte to high gl...
Memory foam
Memory foam is polyurethane with additional chemicals increasing its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (see LRPu)....
Sorbothane
Sorbothane is the brand name of a synthetic viscoelastic urethane polymer used as a shock absorber and vibration damper. It is manufactured by Sorbothane, Inc., based in Kent, Ohio.
Sorbothane was...
Zylon
Zylon (IUPAC name: poly(p-phenylene-2,6-benzobisoxazole)) is a trademarked name for a range of thermoset liquid crystalline polyoxazole. This synthetic polymer material was invented and developed by S...
Polylactic acid
Polylactic acid or polylactide (PLA, Poly) is a biodegradable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), tapioca roots, chips or st...
