barium sulfate manufacturer

Precipitated Barium Sulphate is a white precipitate produced by the reaction of barium ion with sulfate ion solution, which is stable in nature, almost insoluble in water, ethanol and acid, but soluble in hot sulfuric acid, and is the only non-toxic ordinary barium salt.

Precipitated Barium Sulphate has the advantages of strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high whiteness, high gloss, and can absorb harmful X-rays and gamma rays.

Meanwhile, our M Series Precipitated Barium Sulphate has high chemical stability, which can improve the weather resistance, corrosion resistance, and UV resistance of the coating. Due to the low oil absorption of M-series precipitated Barium Sulphate, the coating can still maintain good fluidity even at high concentrations. Adding M Series Precipitated Barium Sulphate to coatings can increase solid content and reduce volatile organic compounds (VOCs). M Series Precipitated Barium Sulphate is easily dispersed in coatings and inks, and can maintain quality stability even after long-term storage. Among various types of coatings, M Series Precipitated Barium Sulphate plays an important role in improving the overall quality of coatings.

3. Plastic

The F Series Modified Ultrafine Precipitated Barium Sulphate from Yunfu Hongzhi New Materials Co., Ltd. is widely used in plastics. It can improve the impact and rigidity of plastics, reduce shrinkage, enhance dimensional stability, and strengthen the wear and corrosion resistance of plastics. The F Series Modified Ultrafine Precipitated Barium Sulphate has a small particle size and high whiteness, which can improve the appearance color of plastics, making them more glossy, bright, and beautiful. It also has good dispersibility and can be evenly distributed in plastics, improving the processability and mechanical properties of plastics. The F Series Modified Ultrafine Precipitated Barium Sulphate is acid and alkali resistant, and does not react with bromine based flame retardants. Adding it to bromine based flame retardant plastics can reduce the precipitation of additives without affecting the flame retardant effect of the formula. In addition, F Series Modified Ultrafine Precipitated Barium Sulphate can effectively reduce the cost of plastics and is a cost-effective plastic additive.

4. Chemical Fibers

The CH Series Modified Precipitated Barium Sulphate from Yunfu Hongzhi New Materials Co., Ltd. has important applications in the field of chemical fibers. The CH Series Modified Precipitated Barium Sulphate undergoes special inorganic and organic coating treatment, resulting in high whiteness, no impurities, uniform and narrow particle size distribution, excellent dispersibility, and no secondary agglomeration. It can effectively disperse in the polyester system, improve the processing performance of polyester fibers, prolong the use time of filters, reduce fiber breakage rate, improve fiber dyeability, spinnability, tensile strength, and enable polyester chips and fibers to exhibit excellent optical properties. The good dispersibility of CH Series Modified Precipitated Barium Sulphate ensures its uniform distribution in chemical fibers, improving their physical properties such as strength and wear resistance. At the same time, CH Series Modified Precipitated Barium Sulphate also has certain UV resistance, which helps to extend the service life of chemical fiber products. In chemical fiber production, CH Series Modified Precipitated Barium Sulphate is an effective additive that plays a positive role in improving the quality of chemical fibers.

5. Film (BoPET)

The AB Series Modified Precipitated Barium Sulphate from Yunfu Hongzhi New Materials Co., Ltd. has important applications in polyester films (BoPET). Due to the fact that the refractive index of AB Series Modified Precipitated Barium Sulphate is almost the same as PET, it does not affect the transparency of the film. Adding AB Series Modified Precipitated Barium Sulphate can reduce product shrinkage, improve temperature resistance, and increase film crystallinity. Compared to silica, it can reduce PET film haze. AB Series Modified Precipitated Barium Sulphate can increase surface roughness, improve film opening performance, and play a role in anti slip and anti bonding. AB Series Modified Precipitated Barium Sulphate has undergone special surface treatment, resulting in excellent dispersibility and minimal impact on the filtration pressure during extrusion processing. It can also improve the whiteness and glossiness of BoPET, making the film look more beautiful. The good dispersibility ensures the uniform distribution of AB Series Modified Precipitated Barium Sulphate in BoPET, improving the physical properties such as strength and wear resistance of the film. In addition, AB Series Modified Precipitated Barium Sulphate can improve the barrier performance and UV resistance of BoPET, prolong its service life, and play an important role in the production and application of BoPET.

6. Lithium Ion Battery Separator

The H Series High-purity Precipitated Barium Sulphate from Yunfu Hongzhi New Materials Co., Ltd. plays an important role in lithium-ion battery separators and can be used as a ceramic coating agent for separators. On the one hand, it can significantly enhance the mechanical properties of the separator, making it less prone to rupture under external compression, impact, and other conditions, providing reliable physical protection for the battery and greatly improving its safety. On the other hand, the H Series High-purity Precipitated Barium Sulphate has good thermal stability, which can effectively improve the heat resistance of the separator. When heat is generated during battery charging and discharging, it can prevent the separator from shrinking, deforming, or even melting due to high temperature, reducing the risk of thermal runaway. In addition, the H Series High-purity Precipitated Barium Sulphate can regulate the pore structure of the separator, ensuring smooth transmission of lithium ions while preventing direct contact between the positive and negative electrodes, providing strong guarantees for the efficient and safe operation of lithium-ion batteries.

7. Lead-acid Batteries

The H Series High-purity Precipitated Barium Sulphate from Yunfu Hongzhi New Materials Co., Ltd. has important applications in lead-acid batteries. H Series High-purity Precipitated Barium Sulphate is added as a negative electrode additive to the negative plate of lead-acid batteries. Due to its crystal structure similar to that of the discharged active material, it becomes the nucleus for PbSO4 deposition, which reduces the supersaturation during PbSO4 crystallization and prevents the shrinkage of the negative active material. H Series High-purity Precipitated Barium Sulphate is an inert substance with dual chemical and electrochemical stability, which can exist stably in negative electrode active materials for a long time and exert long-lasting effectiveness. The "nucleation" and "isolation" effects of H Series High-purity Precipitated Barium Sulphate persist, making it difficult for Pb particles and PbSO4 particles to merge and maintaining the developed specific surface area of the negative electrode plate. The H Series High-purity Precipitated Barium Sulphate can also improve the capacity and cycling performance of batteries, reduce internal resistance and self discharge rate, and enhance the reliability and safety of batteries.
