ABSTRACT:
A method of mixing filled thermoplastic resins containing particles of resin and filler. The method comprises preheating to about 150 degrees to 250 degrees F., at least the resin particles, and thereafter mixing until plasticized. The filler may also be preheated between 150 degrees and 350 degrees F. This method reduces the mixing time and improves the characteristics of the product.
