Hot Melt Extrusion Technique
Various approaches have been adopted to address this including preparation of solid dispersions and solid solutions. Hot-melt extrusion is an efficient technology for producing solid molecular dispersions with considerable advantages over solvent-based processes such as spray drying and co-precipitation. Hot-melt extrusion has been demonstrated to provide sustained, modified, and targeted drug ...
متن کاملProcess Monitoring of Extrusion Based 3D Printing via Laser Scanning
Extrusion based 3D Printing (E3DP) is an Additive Manufacturing (AM) technique that extrudes thermoplastic polymer in order to build up components using a layerwise approach. Hereby, AM typically requires long production times in comparison to mass production processes such as Injection Molding. Failures during the AM process are often only noticed after build completion and frequently lead to ...

متن کاملMelt Glycolysis of Poly(ethylene Terephthalate) Using Co2-assisted Extrusion
A single-step, extrusion-based process to depolymerize poly(ethylene terephthalate) (PET) is being investigated. The depolymeriza tion is effected by reacting ethylene glycol (EG) with the high molecular weight polymer (glycolysis). The ethylene glycol causes chain scission by attacking the ester linkages along the polymer backbone. The objective is to recover purified low molecular weight olig...
