Monoclinic Zirconia Bodies by Thermoplastic Ceramic Extrusion

Journal of the American Ceramic Society, 2004
Two ultrafine, undoped ZrO 2 powders with median primary particle sizes of 9 and 25 nm were used to prepare ceramic suspensions for thermoplastic extrusion. The organic vehicle consisted of an industrial‐grade poly(ethylene‐ co ‐vinyl acetate) (EVA) or ...

High Density Thermoplastic Polyesters for Sheet Extrusion

Journal of Plastic Film & Sheeting, 1993
High density thermoplastic polyester compositions which had been developed for injection molding were modified for sheet extrusion and thermoforming. Formulations were optimized to enhance processability for ex trusion and thermoforming by increasing melt strength at lower shear rates.

Rheological aspects of thermoplastic foam extrusion

Polymer Engineering & Science, 1981
AbstractSeveral rheological aspects of thermoplastic foam extrusion are described by a phenomenological model of the flow in an extrusion die. The macroscopic effects of the phase change, from a homogeneous polymer melt that contains a blowing agent, to a foam, are described in terms of two dimensionless parameters.

Mixing in processing of thermoplastics by extrusion

Chemical and Petroleum Engineering, 1993
Extruders in which the working component is a screw with continuously decreasing channel depth (Fig. la) are the most widely used. In such a screw, the mixing process begins after loading zone I in melting zone II and ends in feeding zone III. However, mixing in the melting zone occurs only in the melt region and does not affect the solid core, which ...

Process Design for Thermoplastic Foam Extrusion

2014
Depending on the polymer used and the end-use application, thermoplastic foams are produced with densities ranging from 3% to 50% of the polymer density. Higher-density foams utilize chemical blowing agents (CBAs) that decompose to release gas that is dissolved in the melt.

Reactive Extrusion for Thermoplastic Starch-Polymer Blends

2014
This chapter briefly reviews reactive extrusion developments for thermoplastic starch polymers. Then, a case study for thermoplastic starch polymer/biopolyester nanocomposite blend will be examined. In this example, maleic anhydride and dicumyl peroxide were used as cross-linking agent and initiator, respectively, for blending starch and a ...
