Characterization


The characterization of materials is an important part of our research and development activities. Not only that we use traditional test methods. We are also developing new characterization methods and/or modify common once meeting the special needs of the materials/components.


Volume dilatometry

     

Reactive resins show volume shrinkage during curing. For many applications, this is a problem, e.g. for moulding resings or adhesives.
During curing and their lifetime nearly all materials pass through various temperature cycles and thereby undergo significant changes in specific volume. Often, higher demands on the reliability of components ask for life time prognoses with simulation methods. Such computations require precise data of the volume change of materials.

With volume dilatometry, the following properties of materials can be determined:

  • volume shrinkage (in %) during cure,
  • cooefficient of thermal expansion of both the liquid and the solid (cured) resin,
  • specific volume or density as a function of temperature and time,
  • glas transition temperature,
  • monitoring of reaction kinetics.

Depending on the specification of the sample material different measurement setups can be used. These can vary in the used confining fluid (mercury, galinstan) and/or the curing method (thermal-induced cure, light-(UV, blue)induced cure).

Density

     

Measurement / Determination of the densitity of compounds, granulates, powders, liquids and solids at room temperature (25°C) by using a helium pycnometer.

 

Mechanical properties

     

To determine the mechanical properties of components we us the following methods:

  • 3-point-bending test,
  • 4-point-bending test,
  • Drum-peel test,
  • Tension and compression tests,
  • ...
