Polybutenes are liquid, transparent and colorless polymers which are synthesized from C4. Polybutenes are similar to polyisobutylenes, yet differ in some points. Characteristic features of polybutene include low creep, high temperature resistance, good flexibility and chemical resistance to solvents. The polymers essentially differ by the molecular weight and its related viscosity.


Our polybutenes are used in adhesives and sealants, rubbers, and a number of other applications. Among others, these include oils and fluids, as well as films.
