Silica is a crucial material in many industries, including rubber, coatings, and adhesives, due to its unique properties such as high strength, thermal stability, and chemical resistance. However, the synthesis of high-quality silica is a complex and challenging process that requires precise control of reaction conditions to prevent the formation of impurities and ensure consistent product quality. Evonik's DYNASIL P is a high-quality silica product that is synthesized using a safe and feasible synthetic route, making it an ideal choice for a wide range of industrial applications.

DYNASIL P is produced by Ningbo Inno Pharmchem Co., Ltd, a leading supplier and manufacturer of specialty chemicals. The product is based on tetrapropyl orthosilicate (TPOS), also known as propyl orthosilicate or tetra-n-propoxysilane, which is a clear, colorless liquid with a pungent odor. TPOS is a highly reactive silane that can be used as a building block in the synthesis of a wide range of silicates, including silica, zeolites, and hybrid organic-inorganic materials.

The synthesis of DYNASIL P involves the hydrolysis and condensation of TPOS under controlled conditions to produce a high-purity silica product with a specific surface area of around 300 m2/g. The product has a narrow particle size distribution, with an average particle size of around 12 nm, and a high degree of purity, with a low level of impurities such as residual alcohol and water. This makes DYNASIL P an ideal choice for applications that require high-quality silica, such as coatings, adhesives, and rubber.

One of the key advantages of DYNASIL P is its safe and feasible synthetic route. Unlike some other silica synthesis methods that use hazardous reagents and require specialized equipment and expertise, the synthesis of DYNASIL P is relatively simple and can be carried out using standard laboratory equipment under mild reaction conditions. This makes it easy for manufacturers and researchers to use DYNASIL P in their products and applications without having to worry about safety concerns or complex synthesis procedures.

Another advantage of DYNASIL P is its versatility. The product can be easily modified to suit different applications by adding functional groups or by adjusting the synthesis conditions. For example, DYNASIL P can be functionalized with amino, epoxy, or carboxylic acid groups to enhance its compatibility with different polymers or to improve its adhesion to different surfaces. Similarly, the particle size and morphology of DYNASIL P can be controlled by adjusting the reaction conditions, allowing for the synthesis of silica with different properties and applications.

Overall, DYNASIL P is an excellent choice for anyone looking for a high-quality, safe, and versatile silica product. Its unique properties and feasible synthetic route make it ideal for a wide range of industrial applications, from coatings and adhesives to rubber and composites. So if you're looking for a reliable and high-quality silica product, be sure to check out DYNASIL P from Evonik.
