FeltMax™

DURATrax™ Family of Polyurethane Roll Covers

 

Designed for the most extreme conditions

Whether it is sever abrasion, doctoring or temperature, FeltMax ™ can handle it.  FeltMax ™ is revolutionary in that it can handle the higher temperatures found around the size press and inside the dryer hood and still be soft enough (15 P&J) at application temperature to dramatically reduce slippage with the felt.  Finally, a roll cover that is designed for the traction you need, yet also offers the papermaker unsurpassed traction, abrasion resistance, hydrophobicity, thermal stability and doctorability.

Applications

Dryer felt rolls, breast rolls, wire rolls, felt rolls, guide rolls, chemi-washer rolls, paper rolls, forming rolls, lead in & lead out rolls, and other non-nipped rolls.

            Cover Attributes – Advantages & Benefits

  • Traction – Dramatic reduction in felt slippage equals longer clothing life
  • Hydrophobicity – Does not absorb ANY water.  Never needs to be “dried out”.
  • Durability – 5x more abrasion resistant than bone hard rubber(0-1 P&J)
  • Doctorability – Can be doctored with composite, steel, or UHMW (Ultra High Molecular Weight Polyethylene) blades
  • Release – Surface morphology provides for exceptional sheet release
  • Stress Relieved – No “edge lifting” or cracking
  • Thermal Stability – Maintains hardness profile and resists thermal degradation
  • Chemical Resistance – Compatible with virtually all chemicals used with any grade of paper
  • Bond Strength - FeltMax ™ cover’s bond strength exceeds its tensile strength.
