Product advantage 1.Reduce scrap rate and cost 2. reduce dosage 3.Be capable of high Dry Comp.Strength&Green Comp.Strength

Activated Bentonite Clay for Oil Refining

 product feature:

White or light yellow powder

Product performance

 we product calcium and sodium based bentonite powder. Mainly used for cast steel, cast iron and other non-ferrous metal casting.The main advantage for the foundry industry is that decrease content,high strength & humidity sex,strong resistance to clip sand ability.As a result,casting surface is more smooth and clean, the dimension is more accurate,the reject rate is lower and to increase comprehensive benefit.Use sodium base bentonite do bond dosage form of sand, performance is better than the more calcium bentonite.
