Detailed Product Description

APPLICATIONS:
The super ultrafine particle size and narrow particle size distribution permit exceptionally high filler loading without compromising impact strength or ductility.

It has the following beneficial applications:
1) In plastic compounding as reinforcing functional filler in extruded weatherable profiles, conduit and pipes. It typically can substitute up to 20% of existing reinforcing additives such as CPE, MBS.
2) In plastic masterbatch.

Best results can be achieved with good mixing to produce good dispersion and distribution of fine particles in the polymer system.
