Dynamic Mechanical Analysis

DMA curves indicating analysis points. The inflection

point in the storage modulus curve is the preferred

analysis point for Tg

• Test modes - flexure (single/dual cantilever, three point bend), tension, compression and shear
• Temperature range (-150 °C to 600 °C)
• Frequencies (0.01 to 200 Hz)
• Storage modulus (E’), loss modulus (E’’) and tan d (E’’/E’) as a function of temperature
• Glass transition temperature, heat distortion temperature and thermal expansion, Creep, stress relaxation and viscoelastic properties
• Measurements to ISO and ASTM standards
• Good Practice Guide
• Reference specimens

Thermo mechanical analyser
(TMA)

Differential scanning calorimetry

Thermo Mechanical Analysis (TMA)

• Standard and modulated TMA
• Test modes – penetration, expansion and flexure
• Temperature range (-150 °C to 1000 °C)
• Glass transition and coefficient of thermal expansion
• Measurements on difficult geometries (fibres, thin films, PCBs)

Differential Scanning Calorimetry (DSC)

• Standard and temperature modulated options
• Auto sampling (capable of handling 50 specimens)
• Temperature range (-90 °C to 700 °C)
• Glass transition, specific heat, melt and crystallinity, degree and rate of cure, oxidative induction time (OIT)

Thermogravimetric Analysis (TGA)

• Measures weight changes in a material as a function of temperature or tim
• Measurement of a material's thermal stability and composition
• Auto sampling option
• Temperature range - ambient to 1200 °C
• Linear heating rates from 0.1  to 500 °C/min
• Ballistic heating rate >2000 °C/min
• Suitable for measurement on all types of materials (solids, powders, liquids)
