Analysis of the thermal stability
of polymers is important for materials under thermal load such
as polymer insulation for electronics. Determination of the
oxidative induction time (O.I.T.) is a standardized technique
which can be easily carried out using the DSC 200 F3 Maia®.
Presented here is a measurement on PE heated to 210°C under
inert (nitrogen) conditions. After a five-minute equilibration
time, the atmosphere was switched to oxygen; the sample then
began to degrade after 70.97 minutes under oxidizing conditions.
NETZSCH offers
precision thermal analysis instruments including advanced dilatometers (with
a new basic R&D/QC dilatometer),
classical DSC & TGA (with
a new economical DSC), high temperature DSC
to 1650°C for specific heat, very high temperature STA
(TGA-DSC/DTA) to 2400°C (featuring the new STA
409-PC Luxx®), thermal
/ evolved gas analysis with fully-integrated FTIR & MS, plus
high resolution TMA and DMA.
We also feature leading technology for thermal conductivity and diffusivity measurement
as well as refractories testing including HMOR, CIC, and RUL.
