Adopting special ultra-fine processing and surface modification technology, this nano-scale wollastonite powder has good dispersibility in organic and inorganic matrixes, and will not agglomerate. It can improve the tensile strength, flexural strength and thermal stability of composite materials by more than 20%, and has good barrier properties to oxygen and water vapor, which can effectively improve the service life of electronic packaging materials.
The particle size is 50-200 nm, the specific surface area is 15-25 m²/g, the aspect ratio is not less than 20:1, the purity is ≥99%, the thermal conductivity is 0.3 W/m·K, the moisture content is ≤0.1%, the heavy metal content is ≤3ppm, and it is packed in 10kg vacuum sealed bags to prevent moisture absorption and agglomeration during transportation and storage.
It is mainly used in the production of aerospace composite materials, new energy vehicle battery packaging materials, electronic circuit board substrates and other high-end composite products. It can improve the performance of composite materials and meet the high requirements of high-tech industries for material performance, especially suitable for precision electronic equipment and new energy product manufacturing.
