Polyurethane (also known as PU, PUR, and TPU) are elastic-plastic tubes that are naturally resistant to friction, oil, and solvents. That is why they make fantastic additions to the printing, ironmaking, and paper-making industries. They are also naturally resistant to kinking and other issues that can affect plastic tubing, which means they are much less likely to fail when employed on the job. Polyurethane can also be colored to fit a number of different situations and events. Whether your business needs to color code its individual pieces or you just want to liven up your printing press, polyurethane gives that freedom, while also giving the freedom of being chemical-resistant.
