The five step process of Thermoplastic Compounding
Thermoplastic compounding is one of the leading procedures of recycling plastic products at much reduced price. This is an elaborate process where varying kinds of base polymers are compounded along with additives, resins and fillers to manufacture a new product. The increasing popularity of this process has given rise to many companies across the world that specializes in this procedure. The process is as simple as the normal compounding procedure, just like you compound wheat flour with water to make bread dough at home.
In this process of custom compounding several products can be made. Depending on which product is to be manufactured, the type of resin is decided. The company that deals with thermoplastic products knows it well what kind of resins or fillers to be used. Usually the co-rotating twin-screw extruder is used in the process of compounding. No matter which kind of polymer is taken for compounding, the type of the extruder remains the same.

Regardless of the fact, how easy this process of compounding appears, within the extruder several processes of compounding takes place. The basic process of thermoplastic compounding is described with three M’s- Melt, Mix and Meter. In this kind of compounding, mixing of the base polymer with the additives deserves special mention.
Apart from the three M’s mentioned earlier, the process of custom compounding is again defined in five steps that include – Feeding, Melting, Mixing, Venting and Metering. However, the five step process can also be categorized into six step processes, when the glass fibers are added between melting to strengthen the quality of the compounded polymer. Each and every process is quite important here, so as to make sure that the compounding is done well. The basic procedure of every compounding remains this way, although the process may vary a little depending on the consequence.
