3-Ply PVC

3-Ply PVC is a heavier grade of PVC belting, typically suitable for loads up to 20Kg/m. It also resists punctures and wear/tear better than its 2-Ply brethren.

It will typically be thicker than 2-ply, and may require larger drive/tension rollers (see specification details)

Other than this, it is interchangeable with 2-Ply belting, though as it is more expensive, you probably wouldn't want to use it unless you needed its tougher attribute.
