PT ZONE: PET Processing - Extrusion
What About Melt Strength?
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.New Option for No-Dry PET, PLA Sheet
New twin-screw system is based on a conical design.Sustainable Sheet: Placon Closes the Loop on PET Recycling
Placon reprocesses up to 12,000 lb/day of PCR PET to produce its EcoStar line of sheet.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.View More Content in This Zone | RSS | Atom
