barium sulfate manufacturer

Product Introduction:

The SK series precipitated barium sulfate is synthesized and produced by Yunfu Hongzhi New Materials Co., Ltd. using advanced barium carbonate sulfuric acid method. Its biggest feature is its large particle size, high whiteness, high diffuse reflectance, non absorption of visible light, and good uniform light intensity distribution after addition, making it an ideal additive for light diffusion products.

Product advantages:

1. Refractive index:

The refractive index is 1.63-1.65, which is similar to most transparent substrates.

2. High stability:

Good chemical and thermal stability, acid and alkali resistance, and high temperature resistance.

3. High chemical purity:

High purity, high whiteness, L value exceeding 99%, neutral color.

4. Good dispersibility:

After special surface treatment, it has low oil absorption, good dispersibility, and no agglomeration.

5. Controllable particle size and morphology:

Large sized square crystals with a concentrated particle size distribution.

Product application:

SK series precipitated barium sulfate is added to transparent substrates such as PC, PS, PMMA, PET, etc. Their similar refractive indices can maintain good transparency or semi transparency of plastics. Adding it to transparent composite materials does not affect the light quantum efficiency of lighting fixtures, improving the uniform light transmission and anti glare performance of the material. For example, in applications such as lampshades and lighting advertising shells, it can also increase the rigidity and weather resistance of lighting fixtures, reduce shrinkage rate, and reduce light aging and yellowing.

The use of SK series precipitated barium sulfate can form a uniform light distribution, achieve soft transition light diffusion and high-quality light atomization effect, improve the comfort and quality of lighting products, and make the light distribution of lamps more uniform.

SK series precipitated barium sulfate can be used as a filling material for frosted atomization and semi transparent scattering layer in optical thin films. Good dispersibility ensures uniform distribution, reduces light reflection loss at the interface, improves film uniformity and transparency, and also increases the mechanical strength of optical films, improving wear resistance and scratch resistance.

In addition, SK series precipitated barium sulfate is non-toxic to the human body and is a new environmentally friendly material, which is very suitable for application systems that require high-purity inorganic materials.
