METHOD OF CONTROLLING PARTICLES SIZE OF FILLERS IN EXTRUDABLE COMPOSITIONS, COMPOSITIONS COMPRISING THE FILLERS AND DEVICES MADE FROM THE COMPOSITIONS

A method of controlling a particle size distribution of a filler in an extrudable composition comprises introducing an extrudable composition comprising a polymer matrix material and a filler into an extruder, the filler having a first average particle size that is larger than a target average parti...

Zusammenfassung:	A method of controlling a particle size distribution of a filler in an extrudable composition comprises introducing an extrudable composition comprising a polymer matrix material and a filler into an extruder, the filler having a first average particle size that is larger than a target average particle size. The extrudable composition is extruded one or more times using the extruder to reduce the size of the filler from the first average particle size to a reduced average particle size, the reduced average particle size being within 10% of the target average particle size.
