Polyurethane vs. Pvc

Views: 70


(organic chemistry) Any of various polymeric resins containing urethane links; used in very many industrial and domestic applications.


a polymer of vinyl chloride used instead of rubber in electric cables


any polymer containing [-NH.CO.O-] linkages; such polymers are much used as the basis of light but rigid foams for packaging (polyurethane foam) and for hard coatings, as on floors.


irregularity of cardiac rhythm; recurrent occurrences can be a precursor of ventricular fibrillation


any of various polymers containing the urethane radical; a wide variety of synthetic forms are made and used as adhesives or plastics or paints or rubber


a synthetic resin in which the polymer units are linked by urethane groups, used chiefly as constituents of paints, varnishes, adhesives, and foams

‘five coats of polyurethane’; ‘polyurethanes serve a variety of uses’;


coat with polyurethane paint or varnish

‘the sanded and polyurethaned floorboards’;


Polyurethane (often abbreviated PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials (monomers) and is therefore a class of polymers, rather than a distinct compound.
