Key Considerations for Non Woven Abrasive Discs

When selecting or buying non-woven abrasive discs, it's important to consider the following key factors:

1. Grit Type and Size: The grit size determines the aggressiveness of the cutting action. Finer grits are used for finishing and polishing, while coarser grits are used for more aggressive material removal.

2. Backing Material: The backing material provides the necessary support for the abrasive grains. Common backing materials for non-woven abrasive discs include nylon, polyester, and composite materials.

3. Abrasive Material: Non-woven abrasive discs can be made with various abrasive materials such as aluminum oxide, silicon carbide, and ceramic abrasives. The choice of abrasive material depends on the application requirements.

4. Disc Diameter and Center Hole Size: Consider the size of the disc and the center hole size to ensure compatibility with your equipment.

5. Density and Grade: The density and grade of the non-woven abrasive disc affect its cutting power and durability. Higher density discs are usually more durable and aggressive.

6. Cooling Properties: Some non-woven abrasive discs are designed with special cooling properties to prevent overheating of the workpiece.

7. Application: Consider the specific application for which the non-woven abrasive discs will be used, such as finishing metal surfaces, preparing surfaces for painting, or removing rust and corrosion.

8. Brand Reputation: Choose non-woven abrasive discs from reputable brands known for their quality and durability.

By considering these factors, you can select the most suitable non-woven abrasive discs for your application requirements.
