As a highprecision innovative function filler of nanometerclass, HTM is specially
developed for electronic printing ink and writing ink industry.
The use of complete and uniform film coating technology enables it to have highly efficient
pigment dispersibility and to fully retain each pigment crystal grain around it and well
distribute in resin and solvent so that the intrinsic hiding power and optical performance of
each pigment crystal grain may be maximized to exhibit a purer color image and vividness.
HTM further reduces its oil absorption by complete film coating treatment, thereby reducing
the resign and solvent consumption in formulas. As a result, a better quick drying property is
achieved and volatility be reduced.
Another important application of HTM is its role as a pigment dispersant in color
masterbatch. It is wellknown that most pigments for plastic are expensive. Hence how to
improve the covering power of pigment is a concern of color masterbatch manufacturers. The
wave length, color and amount of the light absorbed, reflected and scattered by varied
pigments are different. The area of pigment that can be used for scattered light determines the
service efficiency of color. Almost all pigments have conglomeration or flocculation in
applications more of less and the service efficiency of pigment will be attenuated due to the
reduction in the scattering area. Research and practice show that HTM may facilitate the
dispersion of pigment during the manufacture of color masterbatch, and the addition of HTM
does affect the color tone of the pigment in products thanks to the fact that the light refraction
factor of HTM is similar to common polymers. Repeated applications and practices indicate
that pigment consumption in color masterbatch grains may be reduced by 10%. In addition,
the Xray nontransparency of HTM allows it to be used for the manufacture of the raw
materials of toys for children (easy to identify after accidental swallowing). HTM is approved
for the product subject to contacting food due to its nontoxic property. HTM conforms to the
Europe 's purity requirement and U.S' codes of food and drug administration. LD5 (Mouse,
