Thermal Insulation Apparatus & Testing Surface Testing & Gel Timers DMA Testing & Application Notes Polymer Standards & Co-Polymers For checking the THERMAL INSULATION properties of your materials, we offer a rapid service to BS874/ISO8301 for measuring the lambda values. Thickness up to 100mm.

DMA (Dynamic Mechanical Analysis) will give you the glass transition (softening point), stiffness (modulus) and damping from -180?C to 400?C in air. These can vary with the vibration frequency and strain amplitude! Also thermal expansion - TMA. Runs can be made in air or liquids (max 150C) or even @ accurately controlled Relative Humidity - RH. DMA is also over 1000 times as sensitive as DSC for milligrams of powders or a single drop of liquid. DETA or Di-electric Thermal Analysis too.

Polymer calibration standards for GPC or Maldi-TOFS. Deuterated polymers and monomers.



Specific Heat (Cp) Testing
Specific heat (Cp) testing on larger gram size samples.
The main problem with using a DSC to measure specific heat is that the samples are so small that they will often not be representative of the bulk sample particularly if it is a composite or multi-phase material.

Using samples of 2 to 25mm thickness by 50 to 60mm diameter (or octagonal) we can now offer this test over the T range from 0C to 250C. (This is using the same Lasercomp Fox 50 apparatus used for thermal conductivity testing.)
For those with their own Lasercomp apparatus we also offer this software for sale in the UK.
