Expert analysis of plastics

Fischer Ingenieurtechnik has been analyzing plastics and plastic products for the industry for more than 15 years. We analyze and evaluate plastics and plastic products for defects and processing defects. At the same time, we will provide you with information on possible problems and weaknesses.

In addition to the classical mechanical test methods such as

  1. Tensile Testing (Plastics: ISO 527, ASTM D 638 - Fiber Reinforced Composites: ISO 14129 - Soft elastic Foams: ISO 1798, ASTM D 3574 , ASTM D 412, DIN 53504 - Adhesives: ISO 6922)
  2. Compression test (see tensile test)
  3. Impact test (DIN EN 10045, ISO 8256, DIN 53 453, DIN 53 753, DIN 53 448, ASTM D 256, ASTM D 4812)
  4. Vibration test - Determination of Wöhler curves (DIN 50100)
              

also incorporates special analytical methods, such as differential scanning calorimetry (DSC) - dynamic and static DSC tests - in our company.

Differential Scanning Calometrie (DSC)

This process is based on the fact that different materials store different internal (heat) energies. Accordingly, they differ in their thermal capacities, i. In their capacity to absorb or surrender energy.

The DSC test uses this behavior of the plastics: the temperature difference between the sample to be tested and a known reference sample are measured as a function of the heating furnace temperature. This gives information about the specific properties of the plastic sample. Depending on how the sample behaves during heating or cooling, the physical composition of the sample, its molar mass and its thermal history, as well as manufacturing influences during the production of the plastic, can be determined.

The most important digestion of a DSC, however, is that an analysis is carried out using simple means, whether the plastic has already been damaged as a pipe material in advance, or whether damage to the plastic occurred during production due to too much heat or mechanical influence.

It is also possible to determine whether a plastic has been mixed with another plastic, whether it has been improperly mixed with recycled material, or if there are other substances in the plastic which do not belong there and which have led to a change in the properties.

              

In other words, the DSC test allows you to check into the plastic product whether a damage has already been caused by the raw material or by an incorrect processing.

  • Melting point / melting range
  • Heat capacity
  • Crystallization
  • Glass transition
  • Identification
  • Thermal stability
  • Decomposition temperature
  • Oxidation time (OIT)

We determine parameters of plastics according to the following standards:

  • ISO11357-3 Determination of enthalpy / temperature of melting point and crystallization
  • NEN-EN 728 Determination of oxidation induction time
  • ISO11357-4 Determination of Specific Heat Capacity
  • ISO22768 Rubber, Determination of glass transition temperatures with DSC
  • ASTM E1269-05 Determination of specific heat capacity DSC
  • ASTM D1519-95 Rubber, Determination of melting range
  • ASTM D3418-03 Transition temperature of plastics with DSC

Quick processing and expert opinions are our most important corporate objectives, so we are sure that you will be able to convince you about the services of our office.
