Application

Polybutenes serve a diverse range of functions due to their versatile properties. With an isotactic arrangement of ethyl side groups along their linear chains, they form a stable crystalline structure with a helical conformation. Known for their strength and durability, polybutenes boast high tear, impact, and puncture resistance, as well as low creep and excellent chemical and abrasion resistance. Their hydrophobic nature makes them ideal for derivatization into detergents and anti-rust additives. Additionally, they enhance adhesives and coatings by adding tack, flexibility, and water repellency, and contribute to the "cling" properties of LLDPE films. Furthermore, polybutenes act as plasticizers in polymers, and are utilized in the formulation of lubricants and metal-working fluids, showcasing their broad utility in various applications.
