Applicable Base Polymer Properties

Butyl rubber is an elastomeric polymer that is used in a wide variety of construction adhesives and sealants. Because of its unique properties it also is used in the automotive and food processing industries among others. Butyl adhesives can be applied in a number of different forms. It is used widely as a hot melt, solvent solution, preformed tape or gasket, and as a gun-dispensable sealant. Butyl rubber can be used as a primary base resin or as an additive for tack and other desired properties.

Resulting Properties

The cohesive strength of butyl adhesives can be improved by the incorporation of high molecular weight PIB. The modification also provides a degree of age resistance for long-term service. The formulation above is for a hot melt applied PIB modified butyl PSA. It is commonly used for tapes and labels.
