The role of polyurethane diameter increasing sleeve mainly has the following two points: improve the quality of strip: polyurethane diameter increasing sleeve can protect the edge of the strip, reduce or eliminate the generation of strip indentation, so that the strip is steel

The role of polyurethane reducer sleeve is mainly as follows:

Improve strip quality: Polyurethane reducer sleeve can protect the edge of the strip, reduce or eliminate the generation of strip indentation, so that the quality of the strip can be greatly improved.

Save and reduce costs: The polyurethane diameter increasing sleeve for uncoiling machine can realize the rapid replacement of different coil inner diameters in a short time, saving and reducing costs for enterprises.

In addition, because the groups contained in the polyurethane macromolecules are all strong polar groups, and the macromolecules also contain polyether or polyester flexible segments, the polyurethane diameter increasing sleeve has high mechanical strength and oxidation stability, good wear resistance, wide and adjustable hardness range, tear resistance, high bending strength, tensile strength and elongation at break. At the same time, it also has high flexibility, resilience, excellent oil resistance, solvent resistance, water resistance and fire resistance.
