Polybutenes (PB) and polyisobutylenes (PIB) are highly versatile hydrocarbon polymers that occupy a space between conventional polymeric viscosity modifiers and synthetic base stocks. Available across a broad range of molecular weights and viscosities, these materials offer cost-effective thickening and excellent resistance to permanent shear.
Polybutene and PIB chemistries can be tailored to applications ranging from lubricants and greases to specialty fluids where viscosity, tackiness, and long-term performance must be carefully balanced. Differences in molecular structure, molecular weight, and branching provide formulators with additional flexibility beyond conventional viscosity modifier chemistries.
Functional Products offers polybutene and PIB solutions under the P Series to help formulators achieve their target viscosity, improve adhesion, and maintain performance under demanding operating conditions. Functionalized polybutenes are also available under the SD Series, providing additional options for applications requiring polar functionality and surface interactions.
Our team can help identify the appropriate chemistry and viscosity grade for your next formulation versus our entire portfolio of VM chemistries.
