Evonik (formerly Degussa AG) HT, hydroxyl terminated liquid polybutadiene rubber POLYVEST HT Overview:

POLYVEST® HT（POLYVEST ® EP HT) hydroxyl terminated liquid polybutadiene is developed and produced by Evonik Degussa AG. It is a stereoselective, low viscosity, hydroxyl terminated liquid polybutadiene with a high content of double bond structure and hydroxyl functional groups.

POLYVEST ® HT hydroxyl terminated liquid polybutadiene has high reactivity and crosslinking density due to its high content of double bonds in the polymer backbone structure and α - Ѡ - terminated hydroxyl functional groups, providing precise chemical modification opportunities. Its performance includes: excellent chemical resistance; High waterproof performance; Excellent electrical insulation properties; High cold resistance; Good solubility in aliphatic compounds, aromatic compounds, and ethers; Good compatibility with hydrocarbon resins and rosin resins; Low moisture permeability and vapor permeability.
