1. Excellent permeability, avoid abrasive belt losing grinding performance because of adhibiting
    scrap, improve grinding  efficiency and prolong the using life.

2. Good heat dispersion to remove a lot of heat  to avoid crack ，while grinding .

3. With good grinding settlement performance to speed up the abrasive dust to drop to the tank
    bottom, to give a good surface finish.

4. Low foaming, resistance to bacteria and deodorizing.
