The Paderborn Material Database is a software tool to administrate and evaluate material data within the field of polymer technology, which has been developed by Polymer Engineering Paderborn (KTP) at the University of Paderborn. In industry’s everyday life, for instance, the viscosity will be evaluated by means of easily and rapidly calculated MFR-values. Yet, these characteristics from single-point determinations are not sufficient as a basis of simulation calculations. For such calculations further and more complex characteristic values are needed (e.g. power law parameters or parameters of the Carreau Law). With PAM these characteristic values can be rapidly and uncomplicatedly be determined. In the usual databases existing on the market the user can draw back on already existing data without the possibility to add new or evaluate own data. With PAM it is now possible to create, evaluate and compare material data sets.

The features in PAM:

Administration of material data

  • Importing and exporting material- and mixing data
  • Importing measurements or manual input
  • Evaluating measurements with different regression functions
  • Searching for and comparing different polymers
Material data administration

Every characteristic value belonging to a material, like thermodynamic data, density, rheological data etc. is administrated in PAM under the following headlines.

Moreover, series of measurements concerning viscosity, density, heat conductivity etc. can be assigned to each material which are shown as data points in the corresponding diagrams (figure 2).

Material data evaluation

With PAM data can be administrated but it can also be evaluated with regard to a simulation calculation. This software tool makes it possible to perform a regression on the basis of an already existing series of measurement and then to calculate e.g. the Carreau coefficients of a viscosity curve (see figure 2).

Import and Export

Material data or series of measurements can either be entered manually or imported from REX, SIGMA, PaDiCAD or Microsoft Exel. Data already entered and edited in PAM can be imported but also be exported to other software tools like for example REX or SIGMA.

Searching

Within the database the user can search for materials, which fulfill certain criteria, e.g. material types or certain zero viscosities (figure 3).

Comparing data sets

With PAM the user can compare up to five different data sets. This can either be done in a table (figure 4) as well as a graphic (figure 5).
