Introducing our high-quality Fumed Silica for composites, designed specifically for professionals in various industries. This versatile product is perfect for enhancing the performance and properties of composites, including strength, durability, and resistance to moisture and chemicals. Our Fumed Silica is manufactured using advanced technology, resulting in a fine, white powder with excellent dispersibility and compatibility with various resin systems. It offers exceptional reinforcement and viscosity control, making it an ideal choice for applications such as adhesives, coatings, sealants, and composite materials. Trust in our Fumed Silica to elevate your composite products to new levels of excellence.
Description:
Resin-based composite materials have the characteristics of light weight, high strength and corrosion resistance. However, in recent years, the material industry and the pillar industries of the national economy have higher and higher requirements for the performance of resin-based materials. Fumed silica is a modification of traditional resin-based materials. As long as the Hydrophilic and Hydrophobic fumed silica particles can be fully and uniformly dispersed into the resin material, the purpose of comprehensively improving the properties of the resin-based material can be achieved, thereby realizing the production of high-performance resin-based composite materials. Fumed Silica Controls Rheology.
The benefits for composites
1. Improve strength and elongation. The strength, toughness and ductility of epoxy resin materials added with silica (fumed silica) are greatly improved.
2. Improve wear resistance and improve the surface finish of the material. Adding nano-scale fumed silica to epoxy resin is beneficial for filament drawing. Coupled with the high strength of nanoparticles, the wear resistance of the material is greatly enhanced.
3. Anti-aging properties. Fumed nano-silica (fumed silica) can strongly reflect ultraviolet rays, and when added to epoxy resins, it can greatly reduce the degradation of ultraviolet rays on epoxy resins, thereby achieving the purpose of delaying the aging of materials.
