Polybutene is a non-polar hydrocarbon polymer hence it has high solubility in aliphatic, aromatic and chlorinated solvents. Polybutenes undergo combustion, pyrolysis, and autoxidation; the latter two can occur during analytical treatment. Plumbing and heating systems made from PB-1 have been used in Europe and Asia for more than 30 years. Due to its high molecular weight, polybutene does not tend to crack when subject to stress and therefore gives the elastic raw material a high level of flexibility. Among others, these include oils and fluids, as well as films. info[at]terchemicals.com. Polybutenes is a hydrophobic material that is derivatized to make anti-rust additives and detergents..
