Barium Sulphate Filler Masterbatches

  • Barium sulphate Filler Masterbatches (Barium sulfate Filler MB), made of highly pury natural BaSO4, can improve plastic properties, reduce product cost, enhance the hardness, rigidity, specific gravity,compression insistance and abrasive insistance of filler product, and also can reduce product contractility and the deformation caused by contractility, can be prolongable for useful life. Good processing, non-toxic, non-moisture absorption. Excellent dispersion and plasticizing, large adding rate, range of 10%-50%. It can replace expensive Tio2 to reduce the cost effectively. So, choosing super white barium sulphate MB not only improve product quality and also reduce prodution cost.
  • Adopted advanced chemical compounding technology, made the particles disassemble fully in the combination reaction to be minimum and uniform for the mean particle size, and plate protective film on each particle, then will get the product with good dispersion, flwability, compatibility and stability properties, etc. it is acidproof, alkaliproof, light fastness, heatproof, low oil absorption, excellent weatherability, good dispersion and flow, few impurity, high whiteness, strong transparence, and high purity, etc.

  • BaSO4 Filler MB, with strong chemical inertness, good stablity, acidproof and alkaliproof, suitable hardness, high specific gravity, high whiteness, harmful ray absorption, is a kind of pro-environment , super micro, non-toxic and tasteless material.


Barium sulphate filler MB widely used in all kinds of chip, helmet and sound shell to improve the acidproof and alkaliproof of final product. And also widely used for braking lining, gym shoes, toy bullet and plastic curtain to increase its weight and the sense of touch.

We have two specifications of BaSO4 Filler MB for customers selection. One type is highly white, mainly used for white products. Another is normal, recommended to be used for natural color or other color beside white products. the prices are different with different specifications!

Product property

High MI PE as carrier, combined with other relative elastomer, additive and super microsized nano BaSO4, made by high temperature banburying, melting plasticizing and air cooling die cut. Mico powder, high specific gravity and good dispersion, adding rate is 10%-50%, accoring to different dosage with different customer. To increse product weight, prevent product defomation, reduce cost and accord with environmental protection standard.

Packing and storage:

  • Woven bag with inner plastic bag, 25kg / bag, stored in dry warehouse. When used as white pigment, can not delivery and store with other colorful material to avoid contamination. Handle with care when loading and unloading to prevent breakage of packages.
