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

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.
