SYLOBLOC® Silicas

SYLOBLOC® antiblocking agents are amorphous precipitated silica particles available in various particle sizes and pore volumes. They are highly dispersible in polymer films like PP, BOPP, PE, PET, and PVC, offering excellent optical properties and low impurities. SYLOBLOC® reduces blocking by adding roughness to plastic films, with larger pore volumes providing better antiblocking efficiency. Different grades are optimized for specific plastics and film thicknesses.a
