Foundry Perlite features
1, the slag and foreign body can be assembled into the casting solution, and the slag and the foreign body can be easily removed.

2, on the surface of the casting solution, the slag and the foreign body are aggregated to prevent the slag and the foreign body from entering the castings.

3, produced by professional manufacturers, always keep quality stable.

4. When using small ladle, it can cover the light - proof reflection, and the operation is convenient.

5, the chemical composition of the casting solution will not be changed.

6. Compared with the same kind, the addition of the weight less, can play a better slag removal effect.
