HYSIL – MICRONIZED SILICA
HYSIL, the brand name of the micronized silica, is a synthetic, amorphous ,porous, free-flowing silica powder.
Typical Properties Unit Typical Value Appearance - Snow-white free flow powder Mean particle size µm 4 to 10 BET surface area m2/g 100 to 400 Pore volume Ml/g 1 to 2 Loss in weight, at 105°C, 2hr % 3 to 6 Loss on ignition, at 1000°C, 2hr % 5 to 10 Oil adsorption g/100g 100 to 300 SiO2 content % 99 min pH (5% aqueous suspension) - 6.5 to 7.2
Grades and Application:
Grades Uses HYSIL – 36 Anti-blocking agent for high clarity PP, PE and PVC blown and cast flims/foils. For preparation of masterbatches of higher concentrations, giving better dispersion. Slip control agent when used in combination with slip aids HYSIL – 46 HYSIL – 56 Used in adhesive paper manufacturing, to enhance absorption, increase clarity and prevents soiling. Used in rubber compounding, to improve mechanical strength and abrasive resistance, speed up curing / vulcanizing, and give better dispersion of additives and colours. Used in paint manufacturing, to impart excellent matt finish to paints, prevents settling of pigments on storage and increases surface area covered per unit of paint.
Packaging	In 20kg in woven bags with PE lining.
