  • Determine material-product compatibility
  • Characterize material behaviour with regard to tags and cleaning products

Tests facilities :

  • X-ray fluorescence
  • X-ray diffraction
  • Atomic emission spectroscopy
  • Infrared equipment
  • Characterization of physico-chemical properties
  • Thermal analyses (DSC, TGA)
  • pH meter
  • Conductivity meter

Accreditations :

ISO/IEC 17025 awarded by COFRAC and LAB GTA 94 accreditation guide

Testing norms :

Standards required for meeting COFRAC LAB GTA 94 requirements and customer needs

Caratérisation d'un produit ou d'un matériau

Non-metal material expertise

Determining the causes of failure and life cycles of polymers and elastomers and their compatibility with other products.

Tests objectives :

  • Determine physico-chemical properties of a material (mainly polymers or elastomers)
  • Conduct comparative studies between two materials
  • Study compatibility of a material and its environment
  • Understand the ageing process by conducting polymer deformulation or hardness measurements

Tests facilities :

  • Analytical Coupling TGA / GC-MS – Thermo Gravimetric Analysis
  • Infrared spectrometry
  • Plasma spectrometry (ICP)

Rubber and rubber-metal materials expertise

Analyze and assess failures and lifetime of rubber-based parts as well as their compatibility with other products.

Tests objectives :

  • Qualify products and parts
  • Analyze failures
  • Develop specifications
  • Assess potential life cycle (standards and specifications)
  • Study rubber compatibility with oil
  • Check resistance to cleaning products
  • Study and develop products for operation at low temperature

Tests facilities :

4 tension/compression testing machines: 0-20kN / 0-100kN / 0-200kN / 0-400kN
Rubber Parts

  • Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), IR Spectroscopy – for physico-chemical analysis of rubber
  • DRC and DRA: Compression set + Residual deformation after elongation
  • Devices for measuring hardness, DIDC, Shore A and D, tension, tear and resistance to low temperatures (TR10 and Brittle point)
  • Equipment for testing pressure resistance (seals, pipes, hoses)
  • Tools for measuring resistance to environmental conditions (heat, oil, coolant, etc.)

Rubber-Metal Parts

  • Instruments for measuring:
    – Static stiffness (before and after ageing, and at high and low temperature)
    – Dynamic stiffness (before and after ageing)
    – Creep and stress relaxation
    – Adhesion
    – Resistance to environmental conditions
