Press Section Covers

VRS POLYDRIVE W

VRS-POLYDRIVE W

Applications: All wet drive roll applications

Technical data

  • Hardness: 20-60 P&J
  • Thickness: 10-25 mm,
  • Colour: Dark blue
  • Thermal resistance: Up to 90°C
VRS-POLYDRIVE W is an extremely wear resistant polyurethane cover for all wet drive positions. Special base layer provides corrosion protection and guarantees cover adhesion to roll shell. Strong and tough material enables the use of softer covers providing better friction properties.

Advantages

  • Excellent wear resistance
  • Softer, higher friction covers possible
  • Material very tough and resistant to cuts
