Overview of Hot Melt Adhesives
2022.01.23
Hot melt adhesive usually refers to an adhesive that is solid at room temperature and becomes liquid after being heated and melted. After coating or wetting the adherend, it can be pressed and cooled to complete the bonding in a short time. Its solid content Is 100%. Hot melt adhesive is a kind of plastic adhesive with good processing performance. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. Therefore, it can be processed into various shapes and used in different environments. Generally, hot melt adhesives are environmentally friendly chemical products that are non-toxic, tasteless, difficult to decompose and deteriorate. Its use conditions are that it has melting sensitivity when heated, changes in viscosity during use, has certain cold and heat resistance, is not easy to oxidize and decompose and deteriorates, has a certain degree of flexibility, and has a wide range of applications.
