Thermogravimetric analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principle uses include measurement of a material’s thermal stability, filler content in polymers, moisture and solvent content, and the percent composition of components in a compound. It is used to analyse the following:

• Ash content in finished rubber product
• Carbon black content in finished rubber product
• Decomposition temperature
• Moisture content of organic and inorganic materials
• Oxidative stability

Differential scanning calorimetry (DSC) is a powerful analytical tool for the identification of various physical properties and thermal transitions of polymeric materials. DSC is used to estimate the melting and mesomorphic transitions along with their entropy and enthalpy. Characterization of glass transition temperature (Tg) and other effects that show either changes in heat capacity (Cp) or latent heat of polymeric materials can be performed using DSC. This analytical tool measures thermal transitions, Cp, and enthalpy through calorimetry. It is used to analyse the following

• Melting point
• Glass Transition temperature
• Heat Capacity
• Cure Enthalpy
