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.
