Modified Barium Sulphate
Hoyonn Modified Barium Sulphate is researched and developed by the company and many local scientific research institutions. It’s produced by advanced synthetic process, special filtering technology, and surface treatment technology.
The modified barium sulphate has better mechanical performances compared to natural barium sulphate or normal precipitated barium sulphate. It has high activation, ultrafine particle size, and can effectively improve the adhesion for the final products.
Hoyonn has been in the mining industry and providing barium sulphate products for 20 years. We offer customized services to satisfy your demand.
Manufacturing Technique of Hoyonn Modified Barium Sulphate
- Selected high-quality barite
- Superfine grinding process
- Special wet modification process
- Drying
Product Features
1. Hoyonn Modified Barium Sulphate has high activation, good compatibility with resin that can improve mechanical performances for the final products. Its filling rate is about 10% higher than other normal filler materials.
2. It has very low oil absorption, and excellent levelness and machining performance.
3. In the powder coating process, it has outstanding dispersivity compared to normal materials.
4. It also has superior gloss and thixotropy.
