barium sulfate manufacturer

Antimony is extremely important for modern industrial production and is an indispensable raw material. Today, antimony is widely used in various flame retardant materials, alloys, semiconductor components, and glass production. It also plays a key role in the pharmaceutical and chemical industries as well as in national defense and military applications, earning it the nickname "industrial MSG."

As a non-renewable resource, the world's proven antimony reserves amount to only 1.5 million tons. The global annual consumption of antimony is around 130,000 tons, with 60% of it used in the production of antimony trioxide. At the current trend, antimony will be depleted in about 12 years.

Antimony trioxide is a widely used inorganic flame retardant that exhibits a good synergistic effect when used with halogen compounds, significantly improving flame retardant performance. It is extensively used in the flame retardant modification of materials such as wires and cables, polyethylene, polypropylene, polystyrene, polyvinyl chloride, epoxy resins, nylon, and polyurethane. However, the raw material for producing antimony trioxide, metallic antimony, is a non-renewable resource with limited global reserves. Therefore, finding alternatives to antimony trioxide has become a hot topic in the field of flame retardancy.

Yunfu Hongzhi New Material Co., Ltd.'s technical team pioneered the "barium carbonate-sulfuric acid method" for producing nano precipitated barium sulfate, and is also one of the few professional manufacturers in the world to master the production technology of high-quality pigment-grade zinc sulfide. In recent years, we have been committed to the development of new inorganic nano-functional powder materials.

Unlike boric acid zinc, hydrotalcite, and other types of synergists available on the market, the 'Multi-effect Flame Retardant Synergist' produced by Yunfu Hongzhi New Material Co., Ltd. has a broad range of substitution and can be used synergistically with antimony trioxide, phosphates, halogen compounds, nitrogen-based flame retardants, and other flame retardants to enhance the thermal stability of materials, thereby reducing the production of flammable gases and providing better flame retardant performance.

For example, in formula system testing: by adding our 'Multi-effect Flame Retardant Synergist' to replace 50% of antimony trioxide Sb2O3, and simultaneously canceling the addition of copper resistance agents, the test results showed: resistance to 280°C for 140 hours without cracking or damage, maintaining good toughness, and passing the 2.5KV breakdown test after aging.

Yunfu Hongzhi New Material Co., Ltd.'s newly launched 'Multi-effect Flame Retardant Synergist' is favored by more and more enterprises due to its good synergistic effect in flame retardancy, its ability to anchor metal ions with inherent catalytic effects (such as copper ions), improving the product's processability, weather resistance, better covering and dyeing effects, and excellent environmental performance. The product has passed SGS testing and certification, complying with EU RoHS directives and REACH requirements.
