Hydrophobic Precipitated White Carbon Black with Small Paiticle Size and High Purity

Product:Hydrophobic Precipitated Silica, Hydrophobic Superfine particle silica powder
CAS. NO.: 7631-86-9
Composition:100% SiO2
JS-682 Precipitated Hydrophobic White Carbon Black is a special type of white carbon black. It is made by precipitating silica from a solution of sodium silicate and sulfuric acid, followed by washing, filtration, and drying. The product has the characteristics of high-specific surface area, narrow particle size distribution, and excellent hydrophobicity.
Hydrophobicity is the main feature of JS-682 Precipitated Hydrophobic White Carbon Black. It has a unique surface treatment to make the surface completely hydrophobic, and it shows excellent dispersion and fluidity in a variety of polymer systems, such as polyethylene, polypropylene, PVC, and polystyrene. The product can significantly improve the flexural strength, compressive strength, and wear resistance of polymers. At the same time, it can reduce the coefficient of thermal expansion, reduce shrinkage during drying, and improve the dimensional stability of the final product.
Applications of JS-682 Precipitated Hydrophobic White Carbon Black are extensive, especially in rubber and plastics industries, such as tire industry, shoe sole industry, cable insulation and sheath, and electronic packaging materials. In addition, it can also be used as a functional filler in coatings, adhesives, and sealants, effectively improving the performance of the final product. The product is widely recognized by customers for its high quality, stable performance, and excellent cost-effectiveness.
JS-682 Precipitated Hydrophobic White Carbon Black is a valuable product in the field of materials science. It has improved the properties of polymer products, extended their service life, and promoted their development in various applications, making a great contribution to the development of the industry.
