Do you know the composition of hot melt adhesive

      The general components of hot melt adhesives are organic synthetic materials, and the usual components are as follows: binder or main material, tackifier, plasticizer or softener, filler, antioxidant, Modifier.

 

     Among them, the binder (main material) is the main component of the hot melt adhesive, which basically plays a decisive role in the bonding strength, heat resistance, toughness, and medium resistance of the hot melt adhesive. It is usually composed of one or more High-molecular polymer composition. Some plasticizers or softeners are also called tougheners, which can improve the peeling resistance and impact resistance of the adhesive, and it is also helpful to improve the weather resistance of the colloid. The filler generally uses inorganic substances that do not react with the components, which are used to increase the viscosity of the colloid, reduce the expansion coefficient, and improve the impact resistance and mechanical strength.
