EVAL™ Processing / Basics / Start-up, Purging & Shutdown procedure

Start-up, Purging & Shutdown procedure

When processing any polymer, it is important to obtain a homogeneous, completely melted and well-mixed mass at a uniform temperature. It is not only important to have a properly designed machine and good processing conditions. The start-up, purging and shutdown procedure is also very important when processing EVAL™ resins because it determines the quality of the final structure.

A lot of attention has to be paid to the processing equipment, but also to the peripheral units, such as feeding lines, suction tubing, conveying systems and hoppers.
