It is possible to characterize the shear thinning behavior of thermoplastic materials using a Flow Rate Ratio (FRR) test method in an extrusion plastometer (melt indexer). This test method, “Procedure ...

An international team of researchers have observed a phenomenon called virtual melting in colloidal crystals. They studied how it helps enable changes from one crystalline structure to another Virtual ...

Researchers have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many potential groundbreaking ...

ABSTRACT By means of finescale modeling [large-eddy simulation (LES)], the combined effect of thermal and mechanical forcing on the dispersion of a plume in a convective boundary layer is investigated ...

A common problem encountered when extruding plastics is that they show melt fracture or ‘shark-skinning’. This is seen as a jagged surface on the extrudate. The problem is caused by the extrudate ...

Researchers focused on the melting of relatively simple layered materials that, when heated up and put under the pressure of two graphene layers, melt in ways that do not adhere to prior ideas of how ...

Screw design firm Barr Inc. introduced a new VBET-brand screw, which increases the conductive melting capacity and achieves greater melting rates with improved extrudate qualities, with low shear.

Continuous manufacturing of amorphous solid dispersions in a twin-screw extruder is well-suited to quality by design processes such as defining design space. The continuous process of hot-melt ...
