- SPHERILEX® 60 AB was developed for blown and cast film produced from polyolefins and polyesters.
- SPHERILEX® 30 AB is specially designed for very thin films such as biaxially oriented film applications.
Evonik has introduced two new grades of precipitated silica for use as antiblocking agents: SPHERILEX® 60 AB and SPHERILEX® 30 AB.
Antiblocking agents are essential additives in the production of plastic films. These additives help facilitate film winding operations and improve the handling properties of films during subsequent pro¬cessing.
Both SPHERILEX® grades are produced using a new, patented manufacturing process that simultaneously allows spherical particle shape, controlled particle size, and narrow particle size distribution to be achieved. SPHERILEX® 60 AB was developed for standard films based on PE and PP, whereas SPHERILEX® 30 AB is specially designed for very thin films such as biaxially oriented films.
