Basics of Polymer Process Design

FIGURE 1.16 The effect of melt temperature on the film tear strength of polybutylene film extruded at the rate of 10 m/min. The film thickness is 0.002 in. and the blow up ratio is 2.8.

In order to design and analyze polymer processes there are common steps associated with nearly every process. Following Tadmor and Gogos (1979), these basic steps are given below  

These basic steps are based on the following concepts  

Transport phenomena— fluid mechanics, heat transfer, and mass transfer
