What is polyurethane?
Polyurethane is a flexible plastic, an elastomer. The scientific answer is that polyurethane is a polymer (a material composed of many repeating chemical subunits) which has urethane as a repeating unit. Precisely, a urethane chemical group is a collection of 5 specific atoms (two oxygen, one nitrogen, one carbon, and one hydrogen) arranged in certain way.
A polyurethane is any polymer consisting of a chain of organic units joined by urethane links. It is widely used in flexible and rigid foams, durable elastomers and high performance adhesives and sealants, fibers, seals, gaskets, condoms, carpet underlay, and hard plastic parts. Polyurethane products are often called “urethanes”. They should not be confused with the specific substance urethane, also known as ethyl carbamate. Polyurethanes are not produced from ethyl carbamate, nor do they contain it. 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. In both cases, the foam is usually behind other materials: flexible foams are behind upholstery fabrics in commercial and domestic furniture; rigid foams are inside the metal and plastic walls of most refrigerators and freezers, or behind paper, metals and other surface materials in the case o

Polyurethane is a substance categorized as a polymer based on its chemical structure. It is an incredibly resilient, flexible, and durable manufactured material. Some polyurethane is categorized as a thermoplastic that resembles other kinds of plastic, metal, or fiberglass. Thermoplastics are rigid and smooth with a sealed surface impermeable to water. These are used when strength and durability are important, such as in seats at an airport terminal or packaging crates on a truck. As an adhesive, polyurethane resists moisture and heat, so it’s ideal for use in the sun or ocean. It insulates walls, temperature-controlled vehicles, and consumer coolers.
Polyurethane is a foam type product, however it has more structural integrity than the Styrofoam mouldings. Polyurethane is injected into moulds that are then encased, thus allowing the expansion of the foam to occur within the mould. This allows a stronger bonding of the foam. Polyurethane manufacturers can be very creative in regards to their product offering and designs. This product may not be used in construction depending on the building codes and bylaws in certain regions of the country.
