Application

Polybutylene serves as a versatile material known for its unique physical properties and performance benefits. With its continuous linear chain structure, featuring ethyl side groups arranged isotactically, polybutylene forms a stable helical crystalline conformation. This composition grants it high levels of tear, impact, and puncture resistance, along with low creep and excellent chemical and abrasion resistance, making it adaptable and durable for various uses. Additionally, its hydrophobic properties make it suitable for transformation into detergents and anti-rust additives. Polybutylene enhances adhesives and coatings by adding tack, flexibility, and water repellency, and it gives 'cling' properties to linear low-density polyethylene films. It also acts as a valuable plasticizer for polymers, lubricants, and metal-working fluids, broadening its application across different industries.
