The depth of our experience in polymers (materials, processing and design), combined with our comprehensive testing facilities, enables us to provide solutions for a wide variety of problems. The services we offer range from failure analysis and quality assurance, to product consultancy and the development of tailored polymer blends.

Methods of analysis

• Thermal analysis
  

  Differential Scanning Calorimetry (DSC	Glass transition temperature, Melting point, specific heat capacity
  Thermogravimetry (TGA):	Characterisation of elastomers, moisture and filler content
  Dynamic-Mechanical-Analysis (DMA)	Determination of temperature dependent visco-elastic properties
  Dilatometry	Determination of the coefficient of thermal expansion

  
  
• Mechanical testing tensile, comprehensive and flexural tests
  
• Hardness according to Shore A/D
  
• Chemical resistance
  
• Microscopic characterisation
  

  Optical microscopy	microtome sectioning, grinding and polishing
  Scanning electron microscopy
