Choosing
a static mixer requires more than reading a sales catalog and selecting a part
number. Adhesive manufacturers and end
users alike should investigate many variables when evaluating mixer
characteristics for specific applications. This article provides information
intended to help make the right decision when choosing a static mixer to
properly mix a two-component adhesive.
The trend toward increased efficiency, improved safety and alternative fuels in next-generation vehicles is leading to innovations in adhesive and sealant technologies.
Butyl rubber is a copolymer of isobutylene and isoprene. Simple copolymers are known as “regular” or “clear” butyl rubber, or simply “butyl.” When butyl rubbers are modified after polymerization with the halogens bromine or chlorine, a second family, known as halobutyl rubber (or halobutyls), results.
Styrenic
block copolymers (SBCs) used in pressure-sensitive adhesives (PSAs) for
labeling are crucial to formulating adhesives with the desired balance of tack,
peel and shear adhesion.
This
issue of Adhesives & Sealants Industry magazine brings
you our second annual listing of the world’s top manufacturers of adhesives and
sealants. Company rankings are based upon global adhesive and sealant sales for
fiscal 2006, unless otherwise noted.
