The Feature of HJSIL Fumed Silica R274

December 26, 2024

1. High Purity and Quality

Low Impurity Levels: HJSIL Fumed Silica R274 is produced in a controlled environment, resulting in high purity levels that are crucial for many applications, particularly in pharmaceuticals and food products.

2. Fine Particle Size

Nanostructured: The silica has a very fine particle size, typically in the range of 5 to 40 nanometers, contributing to its high surface area.

High Surface Area: With a surface area ranging from 200 to 325 m²/g, R274 offers excellent reinforcement properties.

3. Excellent Thixotropic Properties

Viscosity Modification: HJSIL R274 imparts thixotropic behavior to formulations, meaning that its viscosity decreases under shear stress during application, allowing for easy spreading and flow, then recovers its viscosity when at rest.

4. Reinforcing Agent

Improved Mechanical Properties: It enhances the mechanical strength of various materials, including polymers, adhesives, and sealants, improving tensile strength and tear resistance.

5. Low Bulk Density

Lightweight: The low bulk density of fumed silica means that it is an effective filler, allowing for reduced weight in formulations while maintaining performance.

6. Anti-Caking and Flow Improvement

Free-Flowing Characteristics: R274 is an excellent anti-caking agent for powders, preventing clumping and ensuring consistent flow properties.

Enhanced Handling: It helps improve the flowability of powders in various applications, making it easier to handle and use.

7. High Thermal Stability

Temperature Resistance: HJSIL R274 exhibits high thermal stability, maintaining its properties across a wide range of temperatures, making it suitable for heat-sensitive applications.

8. Hydrophobic and Hydrophilic Grades

Versatile Surface Treatment: Depending on its application, R274 can be treated to be hydrophobic or hydrophilic, offering versatility for use in different formulations.

9. Low Oil Absorption

Efficient Fillers: It generally exhibits low oil absorption characteristics, which is beneficial in keeping costs down and maximizing filler loading in formulations.

10. Low Electrical Conductivity

Electrical Insulator: This silica is non-conductive, making it suitable for use in various electronic applications as an insulating agent.

11. Compatibility with Various Systems

Wide Range of Applications: HJSIL R274 is compatible with a multitude of systems, including polymers, oils, and water-based formulations, making it a versatile additive in numerous industries.

12. Regulatory Compliance

Safety and Approvals: Many HJSIL products meet specific regulatory standards, making them safe for use in food, pharmaceuticals, and cosmetics, aligning with industry regulations for safety and efficacy.

13. Environmental Benefits

Non-toxic and Environmentally Friendly: HJSIL R274 is often regarded as safe for the environment and human health, making it a preferred choice in sustainable product development.
