Indopol® Polybutenes | Rubber Modification


Indopol polybutenes are used as extenders and plasticizers for a variety of vulcanized and other elastomers while offering performance improvements over mineral/process oils.  Polybutenes are compatible with many types of rubber, including: butyl and natural rubber, styrenic block copolymers (SEBS, SIS, SBS), EPDM, styrene-butadiene rubber, polyisoprene, polybutadiene, bromo- and chloro-butyl rubber, and polyisobutylene.


  • Aids in processing of the polymer
  • Acts as an extender of the polymer
  • Modifies the physical properties of the polymer
  • Reduces the viscosity for processing
  • Aids dispersion of fillers, colors & additives
  • Reduces heat during processing

ADVANTAGES - as replacements for process oils


  • Moisture barrier properties
  • Tensile, elongation and tear properties
  • Oxygen barrier performance
  • Low temperature flexibility
  • Chemical and weather resistance
  • Permanency, difficult to extract by solvents
  • Color stability under UV radiation


  • Roofing membranes, rubber sheeting, pipe wrap, conveyor belts
