Key Advantages Inorganic Rheological Solutions
Inorganic additives offer unique benefits for applications requiring extreme performance conditions and specialized formulation requirements.
Extreme Temperature Resistance
Superior thermal stability up to 800°C+ enables use in high-temperature processing and end-use applications where organic additives decompose.
Chemical Inertness
Excellent resistance to acids, bases, solvents, and oxidation. Maintains performance across pH 1-14 range without degradation or color change.
Low Addition Levels
Highly efficient rheological modification at 0.1-5% usage levels. Cost-effective performance with minimal impact on base formulation properties.
Regulatory Compliance
Generally recognized as safe (GRAS) status for many grades. Suitable for food contact, pharmaceutical, and cosmetic applications with appropriate certifications.
Versatile Functionality
Multi-functional performance including thickening, anti-settling, anti-sagging, reinforcement, and barrier properties in single additive.
Application Guidelines
Dispersion Methods
High-Shear Mixing: Use high-speed dispersers or rotor-stator mixers for fumed silica and precipitated silica to achieve proper deagglomeration.
Pre-gel Formation: For clay-based additives, create pre-gel in polar activator before adding to main formulation.
Temperature Control: Maintain appropriate temperature during dispersion to prevent agglomeration and ensure uniform distribution.
Optimization Tips
Surface Treatment: Consider hydrophobic grades for non-polar systems and hydrophilic grades for aqueous systems.
Particle Size: Select appropriate particle size and surface area based on desired rheological profile and transparency requirements.
Synergy Effects: Combine different inorganic additives or blend with organic rheology modifiers for enhanced performance.
