Polybutene is a type of synthetic polymer made from the polymerization of butene, a gaseous hydrocarbon. It is a flexible, rubber-like material that is often used in various applications, including adhesives, sealants, and coatings. Due to its excellent adhesion properties, polybutene is commonly found in products like tapes and labels. This polymer is also utilized in the production of hot melt adhesives and waterproof membranes. Its resistance to moisture and chemicals makes it suitable for use in construction and automotive industries. Additionally, polybutene can be blended with other materials to enhance their performance and durability.
