Changes such as the transition from crystalline to amorphous phases or shifts in vibrational modes can be used to customize the end-polymer's mechanical, thermal, and optical properties to specific ...

Editor?s note: The author, Donald E. De Laney, a consultant in polymer process rheology, worked with GE for 17 years and has worked with Dynisco over the past eight years. The plastics compounding and ...

A presentation at the Leistritz Pharmaceutical-Nutraceutical Extrusion Seminar explained how simulation tools benefit the development process. Twin-screw extruders (TSE) are used in multiple ...

Extrusion is a process used for creating a product (an extrudate) by forcing a material through a die or an orifice to form a shape, or alternatively an extruder is used to produce semi-finished or ...

The authors examine the influence of glass-transition temperature, melt viscosity, degradation temperature, and process settings. Hot-melt extrusion (HME) technology is prominent in the pharmaceutical ...
