Poly(n-butyl vinyl ether) is widely used as a key component in the production of adhesives and sealants. Its excellent flexibility and compatibility with various polymers make it ideal for enhancing the performance of pressure-sensitive adhesives, providing strong bonding properties and durability.

In coatings, it serves as a modifier to improve film-forming characteristics, offering enhanced water resistance and mechanical strength. This makes it suitable for protective coatings in industrial and automotive applications.

Additionally, it is utilized in the formulation of lubricants and plasticizers, where it contributes to reducing friction and improving the workability of materials. Its chemical stability and low toxicity also make it a preferred choice in personal care products, such as hair sprays and cosmetics, where it acts as a film-forming agent.

In the pharmaceutical industry, it is employed as a binder or coating agent for tablets, ensuring controlled drug release and improved stability of the final product.
