Global Medium Molecular Weight Polyisobutylene Market Definition

Medium molecular weight polyisobutylene is employed as a viscosity modifier, tack improver in adhesives formulations, and primary binder in caulking and sealing compounds. It is also used in fuel and lubricating oil additives. It is commonly used as a protective barrier in the adhesive Industry. For example, it is used where exposure to sunlight is a potential risk for sealants. Medium molecular weight polyisobutylene's average molecular weight ranges between 40,000 to 120,000 g/mol.

It is employed in insulating glass sealants and roofing membranes in the construction industry. The copolymer of isoprene and isobutylene is called polyisobutylene. Medium molecular weight polyisobutylene cab is found in a wide range of applications across host industries. Polyisobutylene is used for large volumes in the production of agriculture chemicals, pulp & paper, the inner tubes of tires, chewing gum, sealants and adhesives, caulk, etc. It is typically used in order to achieve desired characteristics in the final products such as higher strength, flexibility, and increased performance in adverse conditions.

Medium molecular weight polyisobutylene exhibits high molecular weight making it impermeable against gases while offering it extended stability at a wide range of temperatures. Additionally, it exhibits a high level of resistance to salts, alkalis, and acids. It offers a cost-effective to achieve low smoke performance in a two-stroke engine. It also offers a wide variety of other benefits such as clean-burning, reduced corrosion, scoring, etc.

Global Medium Molecular Weight Polyisobutylene Market Overview

Growing demand for adhesives & sealants, increasing demand for chewing gum, and rising use of pet bottles are driving the growth of the Medium Molecular Weight Polyisobutylene Market. Enhanced properties of polyisobutylene such as impermeability to gas and moisture are increasing the scope of application such as adhesives, sealants, additives, pharmaceutical stoppers, hosepipes, etc and increasing demand for Medium molecular weight polyisobutylene as a fuel in various industries are boosting the growth of the market.

Moreover, increasing investments in commercial and industrial sectors, the growing trend of strategic partnerships and mergers & acquisitions between vendors, and rapid demand for tires in the automotive industry are providing growth opportunities to the market. In 2015, BASF has acquired the polyisobutylene business of Lanxess AG. The acquisition consisted of mainly intellectual property for new and innovative technology to manufacture polyisobutylene. However, stringent government regulation on the manufacturing and utilization of medium molecular weight polyisobutylene due to increasing potential hazards in the aquatic life cycle can hamper the growth of the market.
