The Universal Selection Source: Adhesives Ingredients

Hot melt adhesives Channel
Hotmelt adhesives are thermoplastics that are applied in a molten state and form a bond on cooling to a solid state. The two important physical properties are: glass transition temperature and melt temperature, varying significantly depending on the type of base polymer used and the additives or modifiers present in the formulation. Major application areas include shoe, automotive, packaging, electrical / electronic, and woodworking.
