N    14:11  Processing Shrinkage diffhist +11,177 Oluschinski talk contribs (Created page with "{{Language_sel|LANG=ger|ARTIKEL=Schwindung}} {{PSM_Infobox}} <span style="font-size:1.2em;font-weight:bold;">Processing shrinkage</span> __FORCETOC__ ==Definition== The term "shrinkage" or "dwindling" generally refers to an irreversible physical process caused by the cooling of an injection-moulded plastic part or the curing of a thermoset plastic. In this process, the volume and dimensions of the moulded part decrease in comparison to the original mould or moulding ne...")
N    13:06  Melt Mass-Flow Rate diffhist +5,728 Oluschinski talk contribs (Created page with "{{Language_sel|LANG=ger|ARTIKEL=Schmelze-Massefließrate}} {{PSM_Infobox}} <span style="font-size:1.2em;font-weight:bold;">Melt mass-flow rate (MFR) (Author: Prof. Dr. H.-J. Radusch)</span> __FORCETOC__ ==Measure of the MFR== The melt index (MFR = Melt Mass-Flow Rate, the former MFI = Melt Flow Index) characterises the flow behaviour of a thermoplastic material. For measuring the MFR, melt index gauge systems, whic...")

Melt index testers are u...")

N    08:46  Density diffhist +16,665 Oluschinski talk contribs (Created page with "{{Language_sel|LANG=ger|ARTIKEL=Dichte}} {{PSM_Infobox}} <span style="font-size:1.2em;font-weight:bold;">Density</span> __FORCETOC__ ==General information== To determine the density, the mass and the volume must generally be determined. The density ''ρ'' of a homogeneous body is defined as the ratio of the mass ''m'' to the total volume ''V'', i.e. {| |- |width="20px"| |width="500px" | <math>\rho\,=\, \frac{m}{V}</math> |} where ''V'' is the volume of the total amou...")

Radusch) ==General principles== Capillary rheometers are used to determine the flow behaviour of polymer melts [1]. Capillary rheometers are characterised by the fact that the fluid to be examined flows through a capillary, which can have a circular cross-section, circular ring cross-section or also a r...")
