Element provides a broad range of analytical testing services for polymeric materials to measure properties such as glass transition temperature, melting point, crystallinity, specific heat, thermal conductivity, storage/loss modulii, modulus changes with frequency and temperature are measured as a function of temperature.
The range of equipment we use to conduct these tests include Dynamic Mechanical Analyser (DMA), Thermo Mechanical Analyzer (TMA), Thermo Gravimetric Analyzer (TGA), DSC Differential Scanning Calorimeter (DSC), Gas Chromatograph (GC-MS), Fourier Transform Infrared Spectroscope (FTIR), High Performance Liquid Chromatograph (HPLC), and optical and scanning microscopes.
These services include:
Differential Scanning Calorimetry (DSC)
DSC is a well known technique for measuring the glass transition temperature of polymeric materials. For thermoplastic materials, DSC is also used to measure melting point, crystallization temperature and degree of crystallinity. For epoxy based anti-corrosion coatings, the degree of cure may be determined. DSC is also used to measure the specific heat capacity of polymers. Element can perform tests using DSC over a temperature range of -170 to 600 °C and according to ASTM D7426-08, F1514-10, D4591-07, E2160-04, D3895-14, D3418-15, ISO 11357.
Dynamic Mechanical Analysis (DMA)
DMA is a technique for investigating temperature and frequency dependent material behavior. DMA can be used to determine glass transition temperature, cure behavior, storage and loss modulii, as well as damping and film/tension behavior. Element can perform tests over a temperature range of -120 to 500C and up to frequencies of 0.01-200 Hz according to the following standards: ASTM D4065, ASTM D 5023, ASTM D5026, ASTM D5418, ASTM D7028 and ASTM E1640.
Thermo-Gravimetric Analysis (TGA)
TGA measures the mass change of a sample as a function of temperature or time, under a defined and controlled environment with respect to heating rate, gas atmosphere, and flow rate. TGA can be used to determine peak temperatures of the 1st and 2nd derivate of the mass changing curve as well as residual mass. TGA can also be used to determine thermal stability and composition. Element offers testing using TGA from room temperature to 1000°C at heating/cooling rate of 0.001 to 200 °C/min. Tests are performed according to ASTM D6370 and D6375.
Thermo Mechanical Analysis (TMA)
TMA determines dimensional changes of solids as a function of temperature and/or time under a defined mechanical force. Element offers testing according to DIN 51 005, ASTM E831, ASTM D696, ASTM D3386, ISO 11359 – Parts 1 to 3. Element’s TMA can operate over a temperature range of -150 °C to 1550 °C.
Gas Chromatography (GC)
Gas Chromatography allows real time quantitative analysis of gas mixtures permeating through polymeric materials (e.g. elastomers, composites) detecting hydrocarbons, CO2 and sulphur based compounds.
Thermal Conductivity Testing
Element can also measure the thermal conductivity of polymers, low conductivity ceramics and glasses in the range of 0.1 to 10 W/m°K over a temperature range of 0 to 190 °C. Tests are performed according to ASTM C 518 and ISO 8301.
Microscopy and Fractography
Element has a number of scanning electron and optical microscopes for microstructural examination of polymeric materials as well as analysis of damaged and failed surfaces.
