HC Plastics News:
The Roller and Belt business of Trelleborg has introduced two upgraded polyurethane rolls for paper towel processing.
One of these products, Rollin Press Plast 4, contains a new polyurethane overlay specifically designed to combine with the rollers during paper processing. It enhances mechanical stress and wear resistance and extends service life. Its hardness is 90-98 Shore A (Shore A).
Sales and business development manager Guillaume Bordais said: "It combines several features that increase productivity. For example, antistatic properties prevent residue on the rollers and make cleaning easier."
The second upgrade, the Press Plast 4D, combines Shore D (Shore Hardness D) and Shore A (Shore A). According to Bordais, the inner layer with a hardness of 90 ShoreA gives the rubber cover a flexibility that can accommodate different settings of the laminate, depending on the configuration of the final product. â€
He added: "The outer layer of hardness of 65 ShoreD allows for perfect bonding between layers, regardless of the number of layers. Applying high pressure to narrow indentations prevents repeated imprinting of the underlying layer."
