Today's hot melt adhesive is still widely used, widely used for bonding and bonding of various products, and more commonly is a PUR hot melt adhesive, so where is the difference between this PUR hot melt adhesive and ordinary hot melt adhesive?
Ordinary hot melt adhesive is a more extensive type of glue, PUR hot melt adhesive is one of them, the general hot melt adhesive is heated coating, laminating can continue to be heated and reused, is a state reversible glue, and PUR is a moisture reaction type hot melt adhesive, the same is heated coating, but after laminating PUR hot melt adhesive will react with the moisture in the air. After the reaction is irreversible (that is, heating will not melt), the high temperature and low temperature resistance of PUR hot melt adhesive is better than that of ordinary hot melt adhesive. However, the specific application should also be selected according to its own product gluing needs.
The packaging of PUR hot melt adhesive is sealed aluminum foil packaging, and the rubber needs sealable professional equipment to better ensure the quality of the film. The hot melt glue machine melts PUR glue by heating it in isolation of air. In the custom furniture woodworking industry, automotive interior, electronic components coating applications, PUR coating quality and product performance is better than EVA glue, in flat paste applications, PUR glue and most of the board good bonding, easy to roll coating, continuous production characteristics, so that it in the production of decorative panels to obtain more and more applications.
Ordinary hot melt adhesive is widely used in automatic packaging, medical and health supplies, logistics express, label tape, automobile, construction, household necessities, shoes, hats and bags and other industries. However, due to the different formulations, for different industries, the application environment may also be different, in the choice of hot melt adhesive need to pay special attention, it is best to talk to the hot melt adhesive manufacturers to clarify their needs and applications, so that manufacturers recommend the right hot melt adhesive.
