Doctor and Roll Cleaning Blade Materials Doctor and roll cleaning blades are used to clean rolls and remove stock accumulations, water, pitch, and filler buildup. With numerous material specifications available, Kadant Solutions’ blades have earned a reputation for precision, efficiency, and reliability. Blade Name Glass epoxy with standard abrasives Recommended for conditioning of dryer surfaces Glass epoxy with coarse abrasives Recommended for conditioning of dryer surfaces Metal with proprietary coating Coating provides enhanced performance with low friction Biovick™ Super Glass epoxy Extra life blade for tough high temperature cleaning applications High carbon bronze alloy Corrosion resistant and good on steel or cast iron rolls Carbon with high temperature resin Long-life carbon fiber blade for sheet shedding positions where high temperature resistance is required Multi-axial carbon fiber, glass fiber, and epoxy resin Excellent solution for high temperature applications Designed for tissue applications that require extended blade life Designed for tissue applications requiring high softness Glass epoxy Extra life blade for tough cleaning applications DriTek™ Bronze Coated bronze Minimizes stickies and coating buildup on the toughest dryer applications High-temperature carbon fiber with coating Excellent at stickies removal and will not spark DriTek™ Steel 100% steel with ceramic coating Minimizes sheet wraps and extends blade life Engineered polymeric Recommended for applications where a thinner, stiff polymeric blade is needed Glass epoxy Roll cleaning applications Glass and carbon epoxy Added strength in the MD, extreme conformability Cotton and phenolic resin laminate Gentle on roll surfaces Glass and proprietary oriented carbon Long life blade aids in the removal of stickies and roll contaminants Glass and carbon fiber with nanotechnology enhanced resin, stickie resistant properties, and metal scrim Long life blade aids in the removal of stickies and roll contaminants Fiberglass with nanotechnology-enhanced resin Stickie-resistant face sheet. Long life blade aids in the removal of stickies and roll contaminants Fiberglass and carbon with nanotechnology-enhanced resin Long life blade aids in the removal of stickies and roll contaminants Fiberglass and carbon with nanotechnology-enhanced resin and stickie-resistant properties Stickie-resistant face sheet. Long life blade aids in the removal of stickies and roll contaminants Carbon fiber with nanotechnology-enhanced resin Long life blade aids in the removal of stickies and roll contaminants Fiberglass and carbon with epoxy resin laminate Excellent for rolls needing increased cleaning capability or extended life Designed for non-polyurethane wet end rolls where extended life is required UHMW polyethylene Designed for all wet end roll applications and is gentle on roll covers PressTek™ Plus Coated stainless steel Designed for difficult shedding positions. Provides long blade life and surface conditioning properties Bi-metal alloy Tough, non-brittle wear resistant alloy with low friction ProCrepe® Plus Bi-metal alloy Tough, non-brittle wear resistant alloy with low friction Bi-metal alloy Tough, non-brittle wear resistant alloy with low friction Carbon/plastic fiber with epoxy resin All wet end positions with reduced frictional drag where a gentle, non-abrasive blade is needed 400 series stainless steel Corrosive applications High carbon steel For most rolls in non-corrosive environments 100% carbon with enhanced resin Long life carbon blade with enhanced cleaning SynTek™ Plus Glass and carbon fiber with enhanced resin Best suited for where nominal cleaning with enhanced life is required Long life carbon blade with excellent cross machine flexibility Carbon fiber with carbide sprayed tip Carbide tip provides long life and wear resistance Glass epoxy Excellent cleaning in high temperature applications Engineered polymeric Recommended for applications where a thinner, stiff polymeric blade is needed Kadant is a global supplier of high-value, critical components and engineered systems used in process industries worldwide.
