Are Reusing the Old PU Rollers Better?
There are countless reasons to choose Polyurethane rollers. No matter you are in food processing, steel, packaging, or printing, the usage of rollers has been found beneficial. One quality that people will look for is wearability. This is an important characteristic of the rollers as the machine undergoes constant pressure during operation, and it is essential to have a roller that can withstand the wear and tear when the machine is used incessantly. This quality, in particular, makes the PU roller the first choice. What is Polyurethane? When Isocyanates and the Polyols react in the catalyst's presence, a polymer named Polyurethane is formed and nearly all compounds formed are thermo setting polymers. These are considered special as they don't melt when heated. Polyurethanes have unique physical properties due to the cross-linking of two compounds. When the cross-linking is high, the more sturdy polymers are found. If the cross-linking is less, then you will obtain soft and del
