This thesis firstly applied four kinds of BaSO_4 in ABS color master batch, using these four additives to substitute certain proportions of pigments,to investigate the variation of coloring effect of ABS color master batch and its products.

The structural design,sieve and development of the core-crust composing color master batch with high concentration are introduced.

Non-poisonous, good light-resistant and heat-resistant color was used for manufacture of the color master batch applied for PP-R, PP-B pipe materials.

There are above 400 color master batch producers in China with a capacity of 300000 t/a and about 98% of the producers adopt dry method process, but the demand all over the country is less than 120000t/a, resulting in serious overcapacity.

Study on Application of Novel Kinds of Carrier Resins in Colour Masterbatch;

The results showed that the quality of colour masterbatch was crucial to the production of PA6 coloured yam,and the required colour masterbatch should be homogeneous and undefiled with paricle size below 1μm and relative viscosity not less than 2.

A review of colour masterbatch and filled masterbatch.

Effect of Nano-BaSO_4 on Color Properties of High Concentration Polyolefine Masterbatch

The surface treated titanium dioxide was used for the manufacture of white colour masterbatch,the dispersibility of TiO_2 in plastic was highly improved,covering power was improved nearly 2.

The dispersibility and covering capability of TiO_2 masterbatch in plastic were both highly improved.
