Medium molecular weight PolyIsobutylenePIB

Product Introduction

The company has a 5000 ton/year polyisobutene plant, which produces typical saturated linear polymers through positive ion polymerization of isobutene. These polymers have the characteristics of not burning or assisting combustion.

Medium molecular weight polyisobutene has colorless, odorless, non-toxic, and excellent acid, alkali, salt, water, ozone, and aging resistance, as well as excellent airtightness and electrical insulation properties. Polyisobutylene has good compatibility with asphalt, wax, polyethylene, etc. Therefore, it has been widely used in adhesion, sealing, insulation glass sealing materials, anti vibration materials, pressure-sensitive adhesives, lubricant viscosity index modifiers, lubricant viscosity enhancers, and gap filling materials, especially in insulation glass sealing materials.
