POLYVEST® eCO HT Bio

POLYVEST® eCO HT Bio is a stereospecific, low viscous and hydroxyl-terminated liquid polybutadiene with a high content of double bonds having the following composition:
· 1,2-vinyl (x) approx. 22 %
· 1,4-trans (y) approx. 58 %
· 1,4-cis (z) approx. 20 %
Our eCO grades present identical physicochemical properties to the traditional POLYVEST® portfolio, as they are based on renewable raw materials according to the mass balance approach.

Typical Applications

In this form POLYVEST® eCO HT Bio is used in various fields of application such as:
  • adhesives and sealants
  • insulated glass sealants
  • waterproofing membranes and coatings
  • gap fillers and expansion joints
  • electrical insulations and potting compounds
  • binder for rubber based sealants and recycled rubber compounds
  • polymer modification
