Description
Barium
Sulfate Precipitated is white powder or ointment made by chemic
sedimentation method, which has an advantage in physical
capability, less mechanical impurity and symmetrical granularity.
It has high density and good filling ability, It is the upper
product that compares with the same kinds in quality in the state.
It has good dispersion, highly whiteness, excellent light fastness,
and acid-resistant. It has an outstanding fire retardant, electric
insulation, chemical inertness and middle surface area. Make it as
functional filler and pigment which has good dispersive and
affinity with other media. It could absorb X-radial and Y-radial
and endow material with high density and the luster of
surface.
APPLICATION: Use:
widely used as filled object for paint, printing ink, rubber,
plastic and insulating tape. Also used in industries of palette,
china, storage battery, porcelain enamel, glass and spice
etc. It
can be applied into paint & coating to control the painting\'s
viscosity, brighten the colors, improve the stability and enhance
the impacting strength of coating products.
To
be used in rubber tires, rubber, plastic sheet, tape, engineering
plastics products for enhancing product\'s anti-aging performance,
can also significantly improve surface smoothness and products\'
hardness to reduce production cost. -Functional
materials To
be used in papermaking materials (mainly for paste products),
flame-retardant materials, X-defense materials, battery cathode
materials. It\'s an indispensable and important component of
concerned materials which able to demonstrate the unique
properties. -Other
field To
be used in porcelain, material for glass, special resin, taken
place the Titanium Dioxide as the white
pigment.
