Product Positioning

Flatness-Oriented Belts for Wide Belt Sanding Systems

Heavy paper backing sanding belts are positioned as flatness-oriented abrasives for wide belt sanding systems.
Rather than extreme tensile strength or aggressive cutting, they focus on stable contact and surface consistency across large sanding areas.

Processing Logic

Why Paper Backing Works Better for Flat Panels

In wide belt sanding, surface quality depends more on contact consistency than peak cutting force.
Heavy paper backing creates a stable contact interface, minimizing waviness, chatter marks, and localized over-cutting.

Backing Structure & Performance Limits

Knowing When to Use—and When Not to Use

• High flatness with low elasticity
• Not suitable for high-tension or heavy impact grinding
• Best for continuous, stable feed applications

Machine Compatibility & Operating Conditions

• Machine type: Wide belt sanders
• Tension range: Medium to low
• Belt speed: Medium to high
• Process type: Continuous sanding
