Introduction to Polybutene
Polybutenes (also called Polybutylenes or Polyisobutylenes) are hydrocarbon synthetic fluids produced by the co-polymerisation of butenes and isobutenes. Polybutenes differ from most other oils by decomposing at temperatures of 250°C to 275°C through a depolymerisation or unzipping mechanism. Polybutene summary: Typically we blend polybutenes with Polyalphaolefin (PAO). Keep in mind…
