Advantages of KUPPER Cerabead:

(1) Powder bulk density(2) Refractoriness(3) Coefficient of
thermal expansion(4) Friendly to Binder

(5) Environment-friendly..

As Kupper CERABEADS is about half as light as zircon and chromite, it can turn out about twice the number of molds per unit weight, and it can be handled so easily, saving labor and transfer power cost.
Having high refractoriness , Kupper CERABEADS can be used for casting various materials, and there is no need to use sand type distinctly according to material.
Thanks to little thermal expansion, Kupper CERABEADS is excellent in dimensional precision.
Kupper Cerabead is a neutral material, so acid, alkali binder can be used,also can reduce usage amount of adhesive
Good recycling performance(more than 50 times). Lower cleavage breakage rate,very low cleavage breakage rate.,easily reclaimed.
