Particle Size and Structure:
 
Fine Particles: HJSIL R274 consists of very fine silica particles, typically ranging from 5 to 40 nanometers in diameter, giving it a high surface area (often around 200 to 325 m²/g).
Amorphous Structure: The structure of fumed silica is amorphous, meaning it does not have a defined crystalline structure. This contributes to its unique physical and chemical properties.
Physical Properties:
 
Lightweight: Due to its low bulk density, R274 acts as an efficient filler in various formulations.
High Surface Area: The high surface area enhances its effectiveness in applications involving thickening, reinforcing, and anti-caking.
Thixotropic Properties:
 
HJSIL R274 exhibits thixotropic behavior, meaning it can alter its viscosity depending on shear conditions. This property is particularly useful in formulations where a change in viscosity with mixing or application is desired.
Reinforcement:
 
It improves the mechanical properties of materials, including polymers, coatings, and adhesives, by enhancing strength, durability, and resistance to wear.
Versatile Applications:
 
HJSIL R274 is used in a range of industries, including:
Cosmetics and Personal Care: As a thickening agent and to improve texture in creams and lotions.
Pharmaceuticals: For use in tablet formulations and as a flow agent.
Coatings: To improve the durability and wear resistance of Paints And Coatings.
Adhesives and Sealants: As a reinforcing agent to enhance bond strength.
Low Oil Absorption:
 
The silica tends to have low oil absorption, making it cost-effective by maximizing filler loading without significantly increasing formulation costs.
Chemical Properties:
 
pH Neutral: HJSIL R274 typically has a neutral pH, making it compatible with a wide range of formulations without affecting their chemical stability.
Hydrophobic and Hydrophilic Forms: Depending on the treatment, R274 can be modified to exhibit either hydrophobic or hydrophilic characteristics, enhancing its versatility for different applications.
