Physical Properties
- Type
– Polyester vs Nylon
- Cost vs performance
- Denier
– Size matters
- Strength
- Flexibility
- Durability
- Cut
Color Dyed vs natural

Phenol vs Urethane
- Phenol attacks fiber
- Phenol is temp resistant
- Urethane is more flexible
- Urethane is more expensive
- Phenol changes color
- Urethane has better adhesion to Nylon

Position of Non Woven products in relation to other abrasive media
Heavy Stock removal Light Stock removal / good finish Conditioning Surface / Good finish Scratch removal / polishing Bonded Abrasives Coated Abrasives
Wire / Filament Products Grit / Set up wheels
Non Woven Products
Polishing Buffs / Wheels
SLIDE 16
Coated vs Nonwoven
- Scratch depth
- Micro deburring
- Consistency of finish
- Lower temperature

Foam Vs. Nonwoven
Foam shares properties of both Coated and Non-Wovens
– Flexibility – Conformability – 2 dimensional abrasive structure – Surface finish changes over time – Shaped forms (built in tool)

Application
SLIDE 24
Fleece
- CF – Nylon, smaller denier, phenolic.
– Handwork, handpads etc. – Light machine finishing
- HD – Nylon, large denier, more resin and grit.
– Heavy Machine Finishing – Intricate Shapes
- SD – Nylon, urethane
– Deburring / Edge breaking – Flexibility to access extreme angles
SLIDE 25
Surface Conditioning Material
- Applications for Belts
– Cookware – Hardware – Metal Fabrication
- Applications for Disks
– Weld blending – Refining Coated abrasive grind lines
SLIDE 26
Technical Wheels
- Unitized
– Deburring – Weld Blending – Cleaning
- Convolute
