2. Surface requirements

Depending on the particular use, some requires surface light or need to be specially processed or treated.

3. Medium high rate

The difference in diameter and end edge diameter of the Polyurethane roller. Its function is to compensate for the flexibility deformation of the slender rubber roller in the operation, and the medium height of the Polyurethane roller increases with the length of the rubber roller.
