Thermal analysis tools

Our laboratory is equipped with a modern, statistical process controlled suite of thermal analysis tools:

  • Differential Scanning Calorimetry (DSC) [material identification, glass transition, melting, crystallinity, residual cure, heat capacity, thermal stability, crystallization kinetics]. ASTM E793, ASTM E794, ASTM E1269, ASTM E1356, ISO 11357
  • Modulated DSC (MDSC) [a sinusoidal temperature modulation is superimposed over a linear ramp, enabling separation of reversing and non-reversing heat flow contributions]
  • Thermal Gravimetric Analysis (TGA) [thermal stability, bulk composition, quantitation of volatiles, residue, loss on drying] ASTM D6370, ASTM E1131, ISO 9924
  • Dynamic Mechanical Analysis (DMA) [tension, compression, cantilever modes; deconvolution of viscoelastic behavior, glass transition temperature, damping characteristics, creep, stress relaxation] ASTM E1640, ASTM D5992
  • Thermal Conductivity [determination of k-value; sub-ambient to elevated temperature measurement; relevant to thermal insulation materials, input for thermal modelling] ASTM C518, ISO 8301
  • Melt Flow Index (MFI) [rate of extrusion of a thermoplastic through a fixed orifice; grade determination, quality control] ASTM D1238, ISO 1133
