Polyisobutylene (PIB) stands as a remarkably versatile and high-performance polymer, essential across a multitude of industrial and commercial applications. As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high purity Polyisobutylene that meets the stringent demands of diverse sectors, from automotive and construction to cosmetics and pharmaceuticals. This saturated aliphatic polymer, derived from the polymerization of isobutene, offers a unique combination of characteristics that make it indispensable in modern formulations.

One of PIB's most significant advantages is its exceptional range of physical properties, which vary depending on its molecular weight. It can range from a viscous oil to a semi-solid to a rubber-like substance, offering incredible adaptability for various needs. Key properties include its very low gas and moisture permeability, making it ideal for barrier applications. It exhibits excellent thermal and oxidative stability, along with superior chemical and ozone resistance, ensuring long-lasting performance in challenging environments. Furthermore, PIB boasts high thickening efficiency, good shear stability, and remarkable electrical insulation properties. It is also valued for its tackifying and adhesive qualities, providing strong bonding and elasticity. Importantly, its low glass transition temperature ensures flexibility even at low temperatures, and its non-toxic nature allows for safe use in sensitive applications such as food packaging and chewing gum bases.

The applications of Polyisobutylene are extensive and continue to grow. In the lubricant and fuel industries, PIB serves as a crucial viscosity modifier, improving the performance of engine oils, industrial gear oils, and greases by enhancing their ability to reduce friction and wear. It is also used as a dispersant and fuel additive, contributing to improved engine efficiency and reduced emissions. For adhesives and sealants, PIB's excellent tackifier and plasticizer properties are highly sought after, providing durable and flexible solutions for pressure-sensitive adhesives, hot-melt adhesives, and sealing compounds in construction and automotive applications. Its waterproofing capabilities are also utilized in roofing membranes and insulating glass units.

In the cosmetics and personal care sector, Polyisobutylene, including its hydrogenated forms, is a popular ingredient. It acts as an effective emollient and moisturizer, helping to restore skin suppleness and prevent water loss. Its film-forming capabilities create a smooth, cohesive, and continuous layer on the skin, enhancing product longevity. As a non-aqueous viscosity-increasing agent, it improves the texture and feel of creams, lotions, lipsticks, and lip glosses, providing a desirable glossy finish. Moreover, its ability to disperse pigments and prevent clumping makes it valuable in makeup formulations, and its waterproofing properties are leveraged in sunscreens to maintain efficacy even after contact with water.

The manufacture of Polyisobutylene involves a sophisticated cationic polymerization process, which demands precise control over reaction conditions to achieve specific molecular weights and desired reactivities. This highly sensitive process typically employs a strong Lewis acid catalyst, often in conjunction with a Lewis base co-catalyst. Various catalytic systems, including those based on aluminum and titanium compounds, are utilized to initiate the polymerization of isobutene. The choice of solvent, whether polar (like chlorinated hydrocarbons) or nonpolar (like alkanes), significantly influences the reaction kinetics and the final polymer structure. NINGBO INNO PHARMCHEM CO.,LTD. leverages advanced manufacturing techniques and rigorous quality control to produce both conventional Polyisobutylene (C-PIB) and highly reactive Polyisobutylene (HR-PIB). HR-PIB, characterized by a high content of terminal double bonds (exo groups), is particularly valuable for subsequent functionalization reactions, enabling the creation of advanced derivatives for specialized applications.

The global demand for high-quality Polyisobutylene continues to rise, driven by increasing needs in automotive, pharmaceutical, and chemical sectors, among others. There is a clear industry trend towards developing more sustainable and environmentally friendly production processes, as well as catalysts that allow for polymerization at milder temperatures.
