Flexible Polyurethane — Flexibly Practical.
Even though it might seem as a niche product with restricted approaches to use it, flexible polyurethane actually has wide-sweeping potentials. It’s very open minded to applications where high performance is vital. That is because it affords qualities like durability, durability, chemical resistance and temperature flexibility which are virtually second to none. As a result, it is ideal for applications such as belting, tank lining membranes, bladders, flexible wall structures and die cuts.
Drive belts, conveyor belts and knitted endless belts all depend on elastic polyurethane. In terms of tanks, the material’s anti corrosive properties render it a suitable membrane liner for vessels sumps, trenches and pits where PVC can not stand up to the task. It’s the toughness of the product’s formula that makes it near puncture proof, thereby preventing spills and leaks of harmful compounds. At the exact same time, liners made from the substance are a fantastic way to include water so as to prevent contaminants from entering . What is more, it does not bond to the concrete which many tanks and vats are produced from. Because of this, it may quickly and cost efficiently be installed in addition to the concrete surface.
Abrasion resistance is just another one of flexible foam’s possessions which make it a top choice for protective coatings such as those required of tank liners polyurea. Even high-impact metals like steel can gain from greater impact absorption via flexible polyurethane surface coating. They can subsequently increase their absorption efficiency thanks to its track record of lasting 25 years or more in highly abrasive environments. Compare that to non-polyurethane-coated steel’s eight-year history and the cost savings over time are undeniable.
Water vessels such as those manufactured by Aire, Maravia and Sotar include flexible polyurethane in their layouts too. The latter two companies coat a few of their boats with the material to improve air retention and abrasion resistance.
Possibly one of its most surprising programs, however, is for medical components. For example, urological catheters, blood flow bladders and heart valves are simply some of the lifesaving manners that the item is set to use in operating and emergency rooms around the world every single day.
Depending on the finish product’s precise film and sheet requirements, elastic foam comes in polyether, polyester and aliphatic-based TPU varieties. Additionally, there are a number of specialty grade elastic polyurethanes readily available, including halogenated and non-halogenated, fire retardant and static dissipative versions. These versions are licensed to conform to many NSF, FDA and European security standards.
