PET Processing - Extrusion
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.
Read MoreExtrusion 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.

Placon reprocesses up to 12,000 lb/day of PCR PET to produce its EcoStar line of sheet.
Read MorePBT & 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.
