Masterbatch method, surface

The surface modification technique of inorganic fillers directly affects the filling modification. The common surface modification methods can be classified into three types inorganic filler pretreatment, blending, and masterbatch methods. 

Special methods of incorporation usually surface modification of filler is performed prior to filler incorporation into the polymer high concentration of calcium carbonate (40 wt%) provides a fihn which has properties similar to paper but surpasses paper in resistance to moisture chlorinated PE containing carboxyl groups was used as compatibilizer with calcium carbonate " masterbatches of titanium dioxide contain 40-50 wt% pigment " rubber modification to incorporate zirconium silicate without a loss of mechanical strength ...
