The differences I know are as follows:

raw rubber, regular rubber and long rubber all have particles.

The particle diameter of raw rubber is larger than the height between the particles and the rubber surface, which is suitable for fast-break play and is not afraid of spin.

The particle diameter of positive glue is equal to the height of the particle from the glue surface.

The diameter of the particles of long rubber is greater than the height between the particles and the rubber surface, which is suitable for chipping. The ball returns weirdly, the ball path is floating, and it has anti-rotation characteristics.

raw rubber is similar to regular rubber and has less friction than regular rubber.
