Lastly, polybutenes are relatively nontoxic when tested in an acute oral test (LDso > 34,600 mg/kg, rat). Due to its chlorine resistance it is commonly found in swimwear. PBT and PET need UV protection if used outdoors, and most grades of these polyesters are flammable, although additives can be used to improve both UV and flammability properties. According to CTFA (2006b), laboratory tests with approved surrogate systems/animals revealed that skin contact testing showed only slight irritation (primary dermal irritation score [PDIS] of 1.5/8.0). 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. 1) Two different spatial arrangements of methyl groups about a double bond in 2-butene give rise to the following geometrical isomers.

Polybutene is a polymer of one or more butylenes obtained from petroleum oils. Main applications are in the electrical and electronics (E&E) industry. Incompatible with strong oxidizing agents. green icon is isolated on white. 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. May react exothermically with reducing agents to release hydrogen gas. Polybutene-1 (PB-1), was discovered in 1954 by the research team of Professor Natta.

Although industrial applications are found in boosting properties such as adhesion, anti-rust and water repellency in coatings, polybutene is also often used in cosmetics such as lipstick formulations. [15], Polybutylene water pipes are no longer accepted by the United States building codes and have been the subject[16] of class action lawsuits in both Canada and the U.S.[17][18] The National Plumbing Code of Canada 1995 listed polybutylene piping as acceptable for use with the exception of recirculation plumbing. The combination of water repelling and sealant properties make polybutenes suitable for corrosion prevention applications. More information about CAS and the CAS registry can be found here. (typically less than 10) The product remains very stable after being prolonged exposure to UV light. Plasticizer for polymers, lubricants and metal-working fluids. An impeller is a part of a pump or compressor that rotates at a high speed and acts as a propeller to increase a fluid's pressure and flow rate. It is used to make up for the shortcomings of polyvinyl acetate hardening when cold, and the population is too soft after saliva, and the amount of polyvinyl acetate accounts. They are designed to meet UL 94 flammability tests as well as Glow Wire Ignition Tests (GWIT), Glow Wire Flammability Test (GWFI) and Comparative Tracking Index (CTI).

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. In the industry, they are especially valued for their low creep, low susceptibility to stress cracks and high heat resistance. It was developed by Britain's Imperial Chemical Industries (ICI).[3]. Decorative Coatings. Polybutene is similar to polyisobutylene (PIB), but the two compounds differ in certain regards. In addition, it acts as a processing aid when added to sealants. Recent Searches.
