High-Performance Bio-based Silica
High-Performance Bio-based Silica is a new type of inorganic functional material integrating environmental protection, multi-functionality and ultra-high performance. It is prepared from renewable biomass such as rice husk, bagasse and plant straw through advanced biosynthetic and precision modification technologies, breaking through the performance limitations of traditional bio-based silica. While retaining the green advantages of low carbon and recyclability, the product achieves precise control of specific surface area, pore structure and surface activity, and has excellent reinforcement, dispersion, matting and heat insulation functions. It is widely used in high-end manufacturing fields such as rubber, coatings, new energy and electronic information, and is an ideal upgrade solution to replace traditional petrochemical-based silica.
Core Features
-
Ultra-High Performance BreakthroughAdopting hierarchical pore structure design and nano-scale particle size control technology, the specific surface area can reach 300-500 m²/g, far exceeding that of conventional bio-based silica. In the field of rubber reinforcement, it can increase the tensile strength of materials by more than 40% and wear resistance by more than 35%; in coating systems, the matting efficiency and gloss uniformity are better than traditional products, without affecting the transparency and mechanical properties of the coating.
-
Extreme Environmental SustainabilityThe raw materials are 100% derived from renewable biomass, and the production process adopts a closed-loop green process, which reduces carbon emissions by more than 50% compared with petrochemical-based silica, and no toxic by-products are generated. The product is biodegradable or recyclable, complying with stringent environmental standards such as EU REACH, RoHS, US TSCA and China GB/T 32163, helping downstream enterprises achieve carbon emission reduction targets.
-
Precision Surface Modification and CompatibilityThe surface is precisely modified with multi-functional groups such as amino, epoxy and silane, and the surface properties can be customized according to downstream application scenarios to achieve molecular-level interface bonding with rubber, resin, polymer and other substrates. It has excellent dispersibility and can be uniformly dispersed in various systems such as water-based, oil-based and solvent-free without special equipment, avoiding agglomeration and improving product processing stability.
-
Multi-Functional Integration AdvantageA single product integrates multiple functions such as reinforcement, matting, heat insulation, insulation and adsorption, and the performance focus can be flexibly adjusted according to application requirements. For example, it can be used as a separator coating material in new energy batteries to improve thermal stability and ion conductivity; in electronic packaging materials, it can enhance insulation and heat resistance; in high-end coatings, it can simultaneously achieve matting and wear-resistant modification.
