The informally abbreviated PU has the letter combination PUR as official abbreviation and combines plastics and synthetic resins. In the concept of Industrial Flooring System, the abbreviation of PU flooring is Polyurethane flooring. Polyurethane floors are usually softer and more elastic compared to other types of industrial floors which makes them more resistant to scratching as their elasticity tends to absorb some of the impact. The elasticity of PU floors also makes them a preferred choice in freezing chambers where the storage temperature can reach -40 degrees Celsius (-40 F). In addition, this floor can be applied over most existing floors.
