Abstract:
A highly filled polymer composition with improved properties comprising:a continuous matrix material; a filler material in an amount of 10 to 80 wt. % of said composition; a polymer plasticizer dispersed in said continuous matrix material in an amount of 0.5 to 15 wt. % of said filler; a filler coating material which coats said filler particles in the form of a continuous coating layer thus forming coated filler particles; a diffusion zone around said coated filler particles where said filler coating and said continuous matrix material are mutually diffused into one another wherein said filler coating material is distributed with concentration decreasing in the direction outward from said continuous coating layer; said filler coating material being selected from the group consisting of a linear low-density polyethylene and polyurethane.
