Polybutenes are clear liquid oligomers typically used as plasticisers, carriers and lubricants which are sold in many different grades determined by viscosity which is related to molecular weight.

The main characteristics are the broad range of viscosities (from 5 cSt @ 37.8ºC to 14.000 cSt @ 100ºC). This reflects the variation on molecular weights which range from 250 to around 4500 g/mol.

The main properties of KEMAT polybutenes are:

  • Non toxic
  • Permanently tacky
  • UV stable
  • Non-drying
  • Corrosion preventative
  • High dielectric properties
  • Thermal stability
  • Soluble in mineral oil
  • Burns without residue
  • Tasteless
  • Odourless
