Valthane™ Series

  • Outstanding Abrasion Resistance
  • Resistance to Cutting & Tearing
  • Excellent Crown Retention
  • Longer Roll Life
  • Resistance Hydrocarbons
  • Heat Resistance to 275° F

Valley Roller’s Valthane™ Series of roll coverings have been found to offer superior abrasion resistance when compared to alternative roll coverings. This family of high-performance covers has been designed to overcome the mechanical and abrasion deficiencies of traditional nitrile Buna, neoprene, Hypalon and other standard roll covers. Valthane™ covers offer performance advantages over a wide range of operating parameters found within a variety of roll applications. Based on innovative rubber chemistry, these unique roll covers offer excellent abrasion resistance, superior mechanical and load bearing properties. In addition, Valthane™ Series roll covers provide chemical resistance to oils, grease and other hydrocarbons.

Valthane™ Series of coverings were designed specifically to improve mechanical properties and abrasion resistance. The heat aging properties are substantially better than other competitive abrasion resistant coverings for the general industrial roll market.

Based on Carboxylated Nitrile polymer, Valthane™ Series roll covers offer outstanding abrasion resistance and compare favorably to liquid cast polyurethane in the hardness range of 45-85 shore A. Good load bearing properties make Valthane™ a good choice but only if line speeds are slower. Valthane™ Series of roll covers are thermally stable up to 275F where the best polyurethane covers begin to degrade at 225F.
