The product is produced by Soleplate process with special treatment small particle size Rutile grade TIO2, It is white powder. It has superior performance and controls molecular weight’s degradation and color fading, keeps product toughness and strength not change still increase; It can effectively overcome the decrease of viscosity and brightness and increase of yellowish caused by degradation of general pigments in PC and other polymers during the processing. Good liquidity, easy dispersion and mixture, high covering power, It makes PC products blight gloss and near natural white color, ensures PC and other Engineering plastic’s optical and mechanics performance.
