Process and Product Development

PPI has the expertise for developing processes involving any of the steps of melting, mixing, reacting, blending and devolatilizing in the preparation of polymer formulations. A classic example is the conversion of a solvent based terpolymerization formerly carried out in large stirred batch kettles into a continuous solvent-free process utilizing a small continuous stirred tank prereactor in conjunction with a twin screw extruder for final conversion and devolatilizing of any unreacted ingredients.

TSMEE: Twin Screw Mixing Element Evaluator

Consequences of changing extruder screw configuration or operating conditions, or varying the protocol of addition of ingredients in formulation of blends or in reactive extrusion can be fully evaluated.
