Many common materials solidify by forming cross-links between molecules. Examples include epoxy and ordinary silicon caulk. Cross-linking is the bonding together of adjacent polymer molecules, often by smaller molecules of another material. Cross-linking occurs in all directions and usually forms a three-dimensional network. Polymers can have thousands of monomers in a single atom, and one polymer molecule can cross-link to many other molecules. This webinar studies the various methods for cross-linking polymer structures, performance properties, and commercial applications.
