Compounding: An introduction
Compounding of plastic is a process that includes melt-blending of plastics with specific additives that are used to change the thermal, physical, aesthetic and electrical characteristics of the material.
Plastics compounding involves an intricate process with multiple stages. These may include determining additives ratio, high-speed mixing via twin-screw extruders, melt mixing, and cooling, all before final pellet cutting and packaging. A range of materials can be used. Those materials include polypropylene, polyethylene, polyvinyl chloride, polystyrene and expanded polystyrene, polyethylene terephthalate, polyurethane, acrylonitrile butadiene styrene (ABS), nylon and other polymers.
