Polymers titanium dioxide pigment incorporation

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 ... 

The client has asked for a recommended formulation for a luxurious soap bar, based solely on vegetable fats (Figure 9.2). A high-quality palm-coconut base that is widely available in Europe should be suitable, but it was felt that such a premium product should contain some additional materials to convey added value .
