Why are film abrasives more stable and less likely to shed grit or deform in continuous sanding?
Why is film abrasive more stable and less likely to shed grit or deform?
In continuous sanding, the main reasons are:
- Higher dimensional stability
Film backing is less likely to curl or deform under heat and pressure changes, keeping contact more uniform.
- More even pressure transfer and scratch pattern
A stable backing helps reduce random deep scratches and improves finishing consistency before polishing.
- Better grit retention in high-frequency work
Film products often maintain cutting performance longer, reducing frequent disc changes.
- Stronger anti-clogging performance with dust extraction
With proper suction and pressure control, film abrasives can deliver more stable durability and process consistency.
