Main applications are in the electrical and electronics (E&E) industry. These catalysts also contain special modifiers, organic compounds belonging to the classes of esters or ethers. Hydrogenated Polyisobutene is an emollient that leaves the surface smooth and soft. Polybutylene terephthalate is used for housings in electrical engineering, but also in automotive construction as plug connectors and in households for example in showerheads or irons. Polybutene's sticky quality therefore is the source of the repellent action of pesticide products containing this active ingredient. PB-1 piping systems are no longer being sold in North America (see "Class action lawsuits and removal from building code approved usage", below). In the industry, they are especially valued for their low creep, low susceptibility to stress cracks and high heat resistance. polybutylene terephthalate (PBT), a strong and highly crystalline synthetic resin, produced by the polymerization of butanediol and terephthalic acid.

In cosmetics and personal care products, it is used in the formulation of lipstick, eye makeup and skin care products. This enables us to improve ads and website content. . In chemical structure Polybutylene (Polybutene-1, PB-1) differs from polyethylene and polypropylene only by the number of carbon atoms in the monomer molecule. Brsenbrcke 2, 20457 Hamburg They are suitable for making lubricants, adhesives, sealants, pipes, rubber and food packaging films. [7] Additional features include excellent wet abrasion resistance, easy melt flowability (shear thinning), and good dispersion of fillers. Butane: Butane is a hydrocarbon that has the chemical formula C 4 H 10. Make it Up: The Essential Guide to DIY Makeup and Skin Care is now available at booksellers all over the world! I love the expensive, substantial feel it adds to lip formulations.
