The Basics of Rubber Base Adhesives

SpecialChem / Andy Extance – Mar 12, 2008

Amongst the many world-changing discoveries made thanks to the journey of Columbus to America, rubber is one of the more overlooked. However, starting from its introduction to Europe and the subsequent invention of the first rubber/solvent suspension at the end of the 18th century 1 , rubber-based adhesives have grown to account for around a third of the world's adhesive use. Rubber-based formulations are now deployed widely, predominantly in pressure-sensitive tapes and labels, construction adhesives, contact adhesives, hot-melts, packaging and high-strength structural applications. Rubber base adhesives are also known as elastomeric adhesives, and their properties normally hinge around elastomer and resin ingredients. If you need to adapt formulation properties, the elastomeric components are a good place to start. The elastomer is a long-chain polymer. The polymer's density, melting point, and boiling point increase with length, which is essentially analogous to the polymer's molecular weight.
