Physico-chemical analysis

01Prerequisites

You need to analyze the material health of your raw materials for production monitoring, part and/or material validation, or R&D purposes.

Etim carries out a wide range of thermal and physico-chemical analyses on raw materials and composite materials, polymers and elastomers, in compliance with existing standards or to our customers’ own specifications…

If you want to compare products, check that your process has been properly transformed, obtain the characteristics needed to size a part or analyze pollution, we can help you analyze your needs and define the right test(s) to carry out.

Our NADCAP qualifications for the aerospace sector, and our specific customer accreditations (AIRBUS, SAFRAN, DASSAULT, etc.) cover a wide spectrum of analyses.

Etim can meet your needs for series production follow-up testing within short deadlines ranging from 1 to 10 days maximum.

Our laboratory is operational all year round, with teams working 2*8 shifts.

03Our services

All our equipment guarantees results in line with current standards (ISO, EN, NF, ASTM, AITM, IGC, etc.).

Thermal analysis

  • ​ATG: mass loss of a material during degradation at temperature and in an oxidizing or inert atmosphere, residue rate of a composite material (glass fibers, carbon, etc.), etc.
  • DSC: determination of a material’s thermal transitions (glass transition, melting temperature/enthalpy, crystallization temperature/enthalpy, polymerization rate, crystallinity rate, etc.), specific heat, oxidation induction time, etc.
  • DMA: measurement of storage modulus, loss, glass transition, master curve (frequency and amplitude variation, etc.)
  • TMA: Measurement of a material’s coefficient of linear expansion from -150 to 1000°C (coefficient of thermal expansion, glass transition temperature, etc.).

Physico-chemical analysis

  • Density measurement (pycnometer method)
  • TVF by acid digestion or dissolution: determination of fiber and resin mass ratios, determination of fiber, resin and porosity volume ratios
  • Surface mass measurement
  • Volatile content measurement
  • Measurement of ash content
  • Flow rate measurement
  • Measurement of water content
  • Measurement of gel time, polymerization kinetics
  • Density and melt flow index measurement
  • FTIR spectrometry analysis: determination of the chemical nature of polymers/paints/adhesives, identification of pollution, identification of organic or inorganic residues…​
