Parameters affecting thermoplastic coating process:Part 2 Available to Purchase

These parameters, therefore, only partly characterise the extrusion performance, and a more valid correlation appears to exist between output rate and the specific energy of mixing and gelation as defined below. A plot of this relation for 15 different compounds at a screw speed of 60 rpm is presented in Fig (6). Energy is absorbed in mixing and gelation and the amount of energy per unit mass of compound increases with increasing output.
