Living fossil quartz powder Modified quartz powder

      Living fossil quartz powder Modified quartz powder 325 quartz powder epoxy casting special silica fume is selected from Donghai County's local high-purity natural quartz (SiO2 content above 99.97%), produced and processed through a unique cleaning and iron-free grinding process. It is white in color and pure in quality. It features chemical stability, resistance to acids and alkalis, large specific surface area, developed porosity, high surface activity, low oil absorption, strong thickening ability, high-temperature resistance, excellent electrical insulation, and UV resistance. With over ten years of production and application experience, Chaori Quartz has mature technology and stable physical and chemical properties, along with a reasonable and controllable particle size distribution. APG Special 325 Active Silica Fume Product Introduction Overview: APG special silica fume is a new product developed based on the characteristics of the APG process in the electrical and electronic industry and the special requirements for fillers. Compared to ordinary active silica fume, this product offers the following advantages: 1. High product purity, low impurities, and significantly better electrical insulation performance than ordinary products. 2. When used in the APG process, it offers excellent fluidity, easy mixing, and easy degassing. 3. Due to its good fluidity, the filling amount can be appropriately increased without affecting the performance of the product. 4. Due to its good light refraction rate, the cast products have bright colors and excellent gloss, making them highly popular among users. 5. High strength. Appearance: White powder, no clumping, no variegated particles. Applicable industries: APG pressure gel, vacuum casting contact boxes, vacuum circuit breaker insulation cylinders, SF6 (sulfur hexafluoride) switch housings, solid-sealed vacuum arc extinguishing chambers, etc.
