Butyl Rubber Adhesive Formulation

Formulation as with other hot melt adhesives butyl rubber based adhesives incorporate polymers a tackification system a diluent and usually a filler.

Butyl rubber adhesive formulation.

Starting point rubber compounding formulations. In stock and ready to ship. These have a service life of 5 15 years depending on the application. The modification also provides a degree of age resistance for long term service.

Butyl rubber sealants can be formulated as well as caulks and extruded tapes. The cohesive strength of butyl adhesives can be improved by the incorporation of high molecular weight pib. The formulation above is for a hot melt applied pib modified butyl psa. Butyl 301 100 nr rss 1 100 100 100 bromo butyl 50 peptizer 0 1 0 1 0 1 nr rss 1 50 zinc oxide 5 0 5 0 5 0.

Natural based adhesives reactive adhesives applicable base polymer. Butyl sealants are elastomer based polyisobutene plastic sealants sometimes called butyl rubber used for sealing applications due to their excellent resistance to uv moisture and ageing. Astm c1085 is a standard specification for a butyl rubber based solvent release sealant with a maximum of 10 joint movement capability. Butyl rubber sometimes just called butyl is a synthetic rubber a copolymer of isobutylene with isoprene the abbreviation iir stands for isobutylene isoprene rubber.

Adhesives formulation applicable type. Because of its unique properties it also is used in the automotive and food processing industries among others. Lack of unsaturation gives butyl rubber adhesives their characteristic oxidation uv and ozone resistance. Automotive buildings constructions assembly transportation excl.

A typical butyl rubber caulking compound has the following composition shown in above. Since the formulation of butyl sealant means that it is already a plastic the term. Its properties do not change over time. Butyl rubber is an elastomeric polymer that is used in a wide variety of construction sealants.

Noncuring butyl sealants with no solvent have long life if used between building panels and in sound deadening applications. Choose from our selection of butyl rubber adhesives in a wide range of styles and sizes. It is commonly used for tapes and labels. Many formulations contain butyl rubber as the only polymer.

These are starting point rubber compounding formulations for providing guide lines only and should be confirmed. Butyl rubber is produced by polymerization of about 98 of. Epoxies ep applicable industrial sectors. Applicable base polymer properties.

They do not harden or oxidize and are not affected by weather.
