Product Overview
Product Overview
This series includes specialty silica gels and catalysts: macroporous microspherical silica gel, spherical aluminosilica gel, column chromatography silica gel, water-resistant silica gel (FNG), and modified copper-silica catalyst. They are widely used in adsorption, drying, chromatography purification, catalyst carriers, and hydrogenation catalysis.
Macroporous Microspherical Silica Gel: Macroporous spherical silica with high surface area, good mechanical strength, and excellent flowability. Used for large-molecule separation, catalyst carriers, and chromatography packings.
Spherical Aluminosilica Gel: Spherical silica-alumina composite with good thermal stability and surface acidity. Used as catalyst carrier, adsorbent, desiccant, and petrochemical auxiliary.
Column Chromatography Silica Gel: High-purity, uniform particle size, suitable for column chromatography. Used for purification of natural products, pharmaceutical intermediates, and organic synthesis products.
Water Resistant Silica Gel (FNG): High water resistance, does not crack or powder easily in water. Suitable for high-humidity gas and liquid drying, such as compressed air, natural gas, and industrial gas dehydration.
Modified Copper-Silica Catalyst: Copper-silica based hydrogenation catalyst for aniline and o-toluidine production. High activity, good selectivity, and long service life.
Application Scenarios and Industry Solutions
Pharmaceuticals & Biotechnology
Used for the separation and purification of natural products, pharmaceutical intermediates, and biomacromolecules. Column chromatography silica gel and macroporous microspherical silica gel provide high purity and high recovery.
Petrochemical & Natural Gas Processing
Spherical aluminosilica gel can be used as a catalyst carrier and adsorbent. Water-resistant silica gel (FNG) is suitable for dehydration and drying of natural gas, compressed air, and industrial gases.
Fine Chemicals & Organic Synthesis
Modified copper-silica catalyst is used for hydrogenation reactions such as aniline and o-toluidine production. Column chromatography silica gel is used for the purification and refining of organic synthesis products.
Why do customers trust us?
What we actually do
Grade selection：We start from your process — what you are drying, purifying or separating — and work back to the right pore structure, instead of quoting you a grade name and hoping it fits.
Customisation：Particle size, pore volume, indicator colour, packaging material and print, managed directly with the production schedule.
Export handling：Documentation (MSDS, TDS, COA, compliance statements), consolidation, and freight options that make sense for your order size.
Technical follow-up：If a batch behaves differently in your line, we trace it back through production records rather than sending you a generic apology.
See it for yourself
We welcome video factory tours and on-site audits. If you want to seethe line that will produce your order, we will arrange it.
