“Fangyuan" FR-761 is a high-grade plastic purpose rutile titanium dioxide produced with sulfuric acid process, This product integrates our innovative research on hydrolysis, salt treatment, calcinations control, inorganic, organic treatment, and product application etc. the surface modified by special organic agents. The product not only has obvious blue bottom phase,high brightness,high dispersion, high hiding power, and provides better pigment performance for the plastic system, but also has lower oil absorption and volatiles, good compatibility and fluidity, and provides better mechanicalprocessingperformance for the plastic system.
★Particle size and distribution
The product particle size is fine and well distributed by our outstanding, hydrolysis and calcining process, which makes it with high gloss, good dispersion, excellent hiding power and tinting strength.
★Surface treatment
We use high quality single aluminum inorganic coating and special organic surface treatment to make FR-761 to achieve the best performance in optical properties and applications.
★Standards adopted
FR-761 meets the following standards:
R2 grade of ISO591;
CAS NO.13463-67-7;
EINECS NO.236-675-5;
Color index NO.77891, white pigment 6
★Applicable scope
Can be widely used in master batch, profiles, plates, pipe such as polyolefin, PvC, ABS, PS etc. also used for leather color paste, oil paint and others.
★Application performance
①Blue under tone: fine particle and good distribution makes it with nice blue tone and excellent whiteness.
②High dispersibility: special inorganic and organic surface treatment makes the product a good dispersibility in application system.
③Low oil absorption: it has good compatibility and dispersibility in plastic resin.
④High temperature resistance: good resistance to turn yellow in the high temperature processing.
★Passed the following SGS tests:
