Molecular Weight (MW) of Polymers

Molecular Weight (MW) testing for polymers and plastics.

Intertek laboratories test for the molecular weight (Mw) for plastics and polymers. The labs provide the number-average molecular weight (Mn), mass-average molecular weight (Mw), z-average molecular weight (Mz) and Polydispersity / Molecular weight distribution (MWD) for a broad range of polymers and plastics. Intertek uses GPC and SEC techniques to analyze organic soluble polymers with MW ranging from 100 - 10.000.000 g/mol.

Molecular weight tests: 

• MW of polymers, soluble in organic solvents (eg. THF, Toluene, Chloroform, DMF, and others)
• GPC (Gel Permeation Chromatography) and SEC (Size Exclusion Chromatography)
  • Gel Permeation and Size Exclusion Chromatography 
  • High Temperature Gel Permeation Chromatography (HT-GPC)
   
• Conventional (calibration based) GPC-DRI (Differential Refractive Index detection) with polystyrene-standard (PS)-calibration or polymethylmethacrylate standards (PMMA)-calibration.
• GPC-UV detection.
• Characterisation of Polymers:
  • Rheologic properties 
  • Optical properties 
  • Mechanical properties 
   

MW analysis techniques: 

• Gel Permeation Chromatography (GPC)
• GPC-UV / RI / SFD / Viscosimetry / ELSD / Light Scattering Detection.
• Multi Angle Laser Light Scattering (MALLS)
• MALDI TOF-MS
• HT- GPC 
• GPC-NMR 

Molecular Weight Determination (MWD) for polymers and plastics: 

• Acrylics, Acrylates, Polystyrene, Rubber
• Polycarbonates, Polysiloxanes
• Resins, Epoxy Resins, Polyester Resins, Silicone Fluids
• Prepolymers, Resins, Polyols, Siloxanes
