2000 Mesh Active Silica Powder is the jewel in the crown of silica powder products, with a particle size of about 4.5 microns, representing the highest level of manufacturing and modification technology in this field. Every step, from the ultimate purification of raw materials (ensuring very low content of radioactive elements like uranium and thorium), to pollution control during ultra-fine grinding, to perfect surface molecular engineering design for the enormous specific surface area, is full of challenges.
The performance gain brought by this product is revolutionary. In the most high-end electronic applications, such as packaging for AI chips and server CPUs, 2000 Mesh Active Silica Powder can achieve a filling rate of over 90%, making the CTE of the packaging material almost perfectly match that of the silicon chip, fundamentally eliminating thermal mismatch stress. Its excellent interface ensures that even at such high filling levels, the material still has good processability and astonishing mechanical strength. In the optical field, it can be used to formulate highly transparent encapsulants to protect precision sensors. In special coatings, it can achieve nano-level smooth surfaces. Due to extremely high technical barriers and costs, 2000 Mesh Active Silica Powder is only applied in the most cutting-edge technological fields where performance is pursued to the extreme and cost is not sensitive. It is a key fundamental material supporting future technological progress.
