Sigma-Aldrich (2) Physical Form. Soltex Polybutene is the tackifier of choice for linear low-density polyethylene (LLDPE) films. You may need to do some re-formulating rather than doing a straight one-for-one swap; you might consider adding some lanolin to get a bit of the tacky richness youll be missing from the polybutene. Being non-polar, polybutenes stick well to other non-polar compounds and do not mix well with water, making them water repellent. Mobile point -37 C ~ 25. PB-1 generally resists chemicals such as detergents, oils, fats, acids, bases, alcohol, ketones, aliphatic hydrocarbons and hot polar solutions (including water). More information about CAS and the CAS registry can be found here.

On the other hand they allow us to improve our content for you by saving and analyzing anonymized user data. Polybutylene is produced by polymerisation of 1-butene using supported ZieglerNatta catalysts. Polybutene is similar to polyisobutylene (PIB), but the two compounds differ in certain regards. In chemical structure Polybutylene (Polybutene-1, PB-1) differs from polyethylene and polypropylene only by the number of carbon atoms in the monomer molecule. At room temperature, it spontaneously converts into the form-I with the melting point of 135C and density of 0.95 g/cm3.[1]. Repeated insult patch tests of 3.150% polybutene in formulations produced, at most, minimal irritation in a small percentage of the test population. Polybutylene (polybutene-1, poly(1-butene), PB-1) is a polyolefin or saturated polymer with the chemical formula (CH2CH(Et))n. Not be confused with polybutene, PB-1 is mainly used in piping.[2].
