BARYTES (Barium Sulphate)

"Barifine B80"

 

Uses: Filler

 

 

An off-white barytes filler for use in elastomers, plastics and friction materials.  Barifine B80 is particularly suitable for use as a low cost alternative to white barytes in applications where high purity is required but high whiteness is not a key requirement.

Other grades are also available.
