Processing
DuPont™ ETPV can be processed by standard thermoplastic processing techniques including:
Injection molding
Extrusion
2K Injection molding
Blow molding
![Page 18: DuPont ETPV Customer Presentation 1 2006](https://reader034.vdocuments.mx/reader034/viewer/2022042623/54f8c2844a79599a0e8b4782/html5/thumbnails/18.jpg)
DuPont™ ETPV 18
Injection molding
DuPont™ ETPV can be injection molded on conventional injection molding machines.
When injection molding soft thermoplastic materials including DuPont™ ETPV, the following elements needs to be considered:
• Sprues and gating (angle & size)• Mold surface treatment (matte)• Injection speed (slow)• Shrinkage (cross & in flow)
DuPont™ ETPV needs to be driedbefore injection molding.Typical melt temperature is 250°C
![Page 19: DuPont ETPV Customer Presentation 1 2006](https://reader034.vdocuments.mx/reader034/viewer/2022042623/54f8c2844a79599a0e8b4782/html5/thumbnails/19.jpg)
DuPont™ ETPV 19
Extrusion
DuPont™ ETPV needs to be driedbefore extrusion. Typical melttemperature is 220°C
DuPont™ ETPV can be extruded with conventional equipment into:
• Hose and tubes• Profiles• Sheets and laminates
When extruding DuPont™ ETPV, the following elements needs to be considered:
• Melt temperature• Screw speed• Draw-down ratio
