Polymers

Versatile polymers can generally be divided into three main groups: thermoplastics, elastomers and thermosets. Their thermal properties can be determined with our thermoanalytical measuring systems in the fields of product development, quality assurance, failure analysis and process optimization.

The No. 1 thermo-analytical method for polymers is DSC (Differential Scanning Calorimetry), with which thermal effects and derivational magnitudes for such properties as melting, crystallization, crosslinking, glass transition, specific heat, and oxidation can be investigated.

TG (Thermogravimetry) provides information about the composition and thermostability of polymer mixtures and blends. In addition, gas analyses with QMS (Quadrupole Mass Spectrometry) or FTIR (Fourier Transform Infrared-Spectroscopy) can also be performed.

Dilatometry and TMA (Thermomechanical Analysis) yield the coefficient of thermal expansion. DMA (Dynamic Mechanical Analysis) also provides values for the coefficient of elasticity and information regarding the visco-elastic behavior, aging, creep and relaxation.

With DEA (Dielectric Analysis), the curing behavior of reactive resin systems can be measured, even during processing.

Using LFA (Laser/Light Flash Analysis), the thermal diffusivity for thermoplastic melts can also be measured and the thermal conductivity can be determined. The thermal conductivity of polymer isolation foams can be measured with the heat flow meter (HFM).
