Key Features

Industry-leading Decolorization Performance (≥270 mg/g methylene blue value)
Ultra-high decolorization capacity, effectively removes trace refractory pigments, achieves extremely high effluent clarity and whiteness.
Top Food Grade Quality
Strict food-grade production control, complete qualification certificates, meets the highest safety requirements of food and pharmaceutical industries.
Optimized Pore Structure
Precision-controlled mesopore distribution, excellent adsorption effect on pigments of different molecular weights, wide application range.
High Adsorption Selectivity
Effectively adsorbs colored impurities while retaining effective product components to a greater extent, reducing product loss.

Applications

High-End Pharmaceutical Precision Refining: High-value APIs, biological agents and pharmaceutical preparations with the highest purity requirements demand ultra-low residual color and impurities. F-18's industry-leading methylene blue capacity removes trace refractory pigments that even F-16 cannot fully capture, ensuring maximum product clarity and regulatory compliance.
Premium Food & Beverage Refining: High-end health products and premium beverages require the strictest visual and taste standards. F-18's ultra-strong decolorization capacity achieves extremely high effluent clarity and whiteness at low dosage, protecting brand quality in luxury product segments.
High-Grade Sugar Deep Decolorization: Refined sugar production targeting the highest whiteness specifications (rock sugar, refined white sugar) requires top-tier decolorization performance. F-18's precision-controlled pore structure removes the last traces of color bodies that lower grades miss.
High-End Fine Chemical Purification: High-value fine chemicals with strict chroma and impurity control need the strongest adsorption capacity available. F-18 achieves extremely high decolorization depth with minimal carbon dosage, reducing both material cost and waste generation per unit of product.
