ADVANTAGES:
Good Collapsibility
Low gas & low Nitrogen evolution
Very good Surface Finish
Specialty of this RCS is excellent flowability, which gives better compactness, and hence there is no porosity in the cores.
Uniform wall Thickness for hollow cores.
Low Rejections
We can also give the grades as per the customer's Specifications.
