One Solution to the Problem Of Char: Metallocene-Based Adhesives

Clear with MetalloceneIn the past few years metallocene-based polymer hot-melt adhesives have become more widely available in the marketplace, and more affordable for use in the packaging field.

Metallocene-based hot melt offers superior performance and char-free operation, because the chemical composition means they are not subject to carbon buildup, gelling, or any other changes over extended high temperature storage and use.

As a result, metallocene-based adhesives can be stored indefinitely in glue tanks at high temperatures. The glue will flow clearly at all times through the application cycle, without char buildup or any other material change. Also, unlike EVA-based adhesive, metallocene-based adhesives won’t cause poor or blocked adhesive flow through pumps, hoses, or nozzles.
