Repeated insult patch tests of 3.150% polybutene in formulations produced, at most, minimal irritation in a small percentage of the test population. Some of the characteristic properties of polybutene include high creep strength (low creep), high heat resistance, high flexibility and resistance to solvents. Being non-polar, polybutenes stick well to other non-polar compounds and do not mix well with water, making them water repellent. Poly alpha olefins (PAO) Poly alpha olefins (PAO) are widely known as PAOs. Localized stress whitening of the material generally accompanies and precedes decomposition of the polymer. The geometrical isomerism arises when atoms or groups are arranged differently in space due to restricted rotation of a bond or bonds in a molecule. Heated up to 190C and above, PB-1 can easily be compression moulded, injection moulded, blown to hollow parts, extruded, and welded.

Lowering seal initiation temperature (SIT) of high speed packaging polypropylene based films. The phase transition rates during deformation with three strain rates show consistent dependence on external work. [19], There is evidence to suggest that the presence of chlorine and chloramine compounds in municipal water (often deliberately added to retard bacterial growth) will cause deterioration of the internal chemical structure of polybutylene piping and the associated acetal fittings. Soltex polybutene exhibits good clarity, durability and cling properties, and has food-grade approval for use in food wraps. From these three building blocks there are three possible types of repeating units in polybutene: derived from 1-butene, 2-butene and isobutylene, respectively and where x, y and z represent various numbers of each repeating unit in one particular molecule of polybutene. [8], International standards set minimum performance requirements for pipes made from PB-1 used in hot water applications.

The molecular weight of the end product is limited by the reaction temperature used in the chamber. It is a thermoplastic polyolefin similar to polyethylene and polypropylene produced through the polymerization of butene-1 using stereospecific catalysts to create a linear, highly isotactic and semi-crystalline polymer. The large non-polar surface area created by these long carbon chains and ease of mixing being a liquid give polybutene its sought after adhesive properties. PBT resists solvents, shrinks very little during forming, is mechanically strong, is heat-resistant up to 150 C (or 200 C with glass-fibre reinforcement), and can be treated with flame retardants to make it noncombustible.
