Abstract
Described herein is a process to prepare plastic masterbatches, compounds, and compositions thereof composed of at least one plastic matrix, at least one low density solvent or low viscosity solvent, optionally at least one dispersant, and at least one type of inorganic particles. The process described herein improves and optimizes migration mechanism of particles to the surface of the compounded plastic composition and reduces the material lost, by first dispersing the inorganic particles in low density solvent or low viscosity solvent followed by extrusion in plastics matrices.
