This product is made of high-purity silicon dioxide raw materials through processes such as high-temperature melting and fine grinding. It has excellent chemical stability, high insulation, low coefficient of thermal expansion, and good dispersibility. It is widely applied in fields such as electronic packaging, coatings, rubber, plastics, ceramics, and composite materials, and can significantly improve the mechanical strength, heat resistance, and insulation performance of products.
Product Overview: This product is made of high-purity silicon dioxide raw materials through processes such as high-temperature melting and fine grinding. It has excellent chemical stability, high insulation, low coefficient of thermal expansion, and good dispersibility. It is widely applied in fields such as electronic packaging, coatings, rubber, plastics, ceramics, and composite materials, and can significantly improve the mechanical strength, heat resistance, and insulation performance of products.
Product Features: High Purity: The content of SiO2 is ≥99%, and the impurity content is extremely low. Excellent Temperature Resistance: Good thermal stability, stable performance in high-temperature environments. Low Expansion Coefficient: Effectively reduces the stress generated by materials due to temperature changes. Uniform Particle Size: Fine classification, controllable particle size distribution, and good dispersibility. High Cost-performance: Superior performance, reasonable price, meeting the needs of different industries.
Application Fields: Electronic packaging materials (epoxy resin, silicone rubber, etc.) High-performance coatings and inks Reinforcing fillers for rubber and plastics Ceramics and refractory materials Modification of composite materials
Packaging and Storage: Packaging: 25kg/bag (customizable packaging is available). Storage: Store in a cool and dry place, avoiding a humid, high-temperature, and acid-base environment.
Precautions Wear a dust mask during use to avoid inhaling dust. Fully mix with materials such as resins to eliminate air bubbles. Remarks: The above parameters are general examples, and specific indicators need to be customized according to customer requirements.
