PET Processing - Extrusion
Calibrate Those Instruments
Make sure that your instruments are calibrated on a regular bases and also do a check and balance when gathering data. Never trust what you think you see the first time.

Extrusion: Where's the Data? The Importance of Melt Strength in Extrusion
All extrusion processes depend to some degree on the melt strength of the polymer, and this property is generally a no-show on data sheets.

Extrusion Without Discolored Specks
Specks are a common problem in extrusion, and avoiding them requires a two-pronged approach: First, figure out how many specks are in the incoming raw material; then minimize those caused during the extrusion process.

PBT & PET Polyester: Part 2 The Performance Factor
All things being equal, PET will outperform PBT mechanically and thermally. But the processor must dry the material properly and must understand the importance of mold temperature in achieving a degree of crystallinity that allows the natural advantages of the polymer to be realized.
