Polyisobutylene (PIB)

Polyisobutylene (PIB) and Polybutylene are liquid polymers produced by the cationic polymerisation of isobutylene and raffinate-1 respectively. We offer a comprehensive product range with molecular weight from 450 to 90,000 MW.

Polyisobutene CAS 9003-27-4 / EC 204-066-3  -  Polybutene CAS 9003-29-6 / EC 203-452-9

We have partnered with TPC Group to bring their range of PIB to Europe.



  • Low gas or moisture permeability
  • Low / non-toxicity & colourless / transparent
  • Water white colour and odourless
  • High thickening efficiency
  • Good shear stability
  • Clean burning / low deposit
  • Good electrical insulation
  • Oxidation stability to light/UV and air
  • Tackifier/adhesive properties
  • Low temperature properties


Main Applications:

  • Adhesives (pressure sensitive adhesives and hot melt adhesives)
  • Electrical insulation materials (cables, condenser…)
  • Intermediate for lubricants and fuels dispersant additives, explosive emulsifier
  • Lubricants and greases (as viscosity modifiers in automotive and industrial gear oils, base oil in 2 strokes lubricants, tackifier in chainsaw and slideway lubricants, bright stock substitute, metal working fluids…)
  • Sealants and caulks
  • Wrap films (stretch films, wrap films for silage…)
  • Others: asphalt modifiers, chewing gum (high MW PIB), personal care (hydrogenated PIB), polymer modifiers, resin plasticizer
