Method A/B is a test that can be performed in a melt flow rate tester so as to calculate the value of the polymer’s melt density at a certain temperature. Both a “method A” test and a “method B” test ...
Semi-crystalline polymers containing amorphous and crystalline regions usually have intimately mixed chains. The resulting topological constraints (entanglements) in the amorphous regions limit the ...

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 ...
A polymer is a chemical compound that contains a large number of identical molecular repeating units. A plastic material is a polymer, typically modified with additives, which can be molded or shaped ...
