Intertek thermal analysis laboratories test materials for their glass transition temperature (Tg). Materials tested for Tg polymers, glasses, thermo-plastics, co-polymers, gels, composites, amorphous metals, proteins, sugars, rubber, pharmaceuticals, adhesives, chemicals and many more.
The glass transition of a material marks the temperature below which amorphous materials behave as a glassy solid and above which the same materials behave as if they are liquids or in a rubbery state.
Physical property changes are measured by the thermal properties labs to help clients determine a material's suitability for specific intended usage. Properties that are affected by the value of glass transition analysis include material hardness (glassy materials are harder than rubbery ones), volume, modulus and percent elongation-to-break.
Intertek Differential Scanning Calorimetry techniques are mainly employed to measure glass transition temperature (Tg) but the Tg parameter can also be determined using DMA (Dynamic mechanical Analysis) or TMA (Therm-mechanical Analysis) depending on the exact nature of the sample.
