Hot melt adhesive stick is a solid adhesive made of ethylene vinyl acetate copolymer (EVA) as the main material, adding tackifier and other ingredients. It has a white opaque (strong) appearance, non-toxic, easy to operate, and continuous use without carbonization phenomenon. 1. Fast bonding The hot melt glue stick can quickly bond materials in a short time and improve work efficiency. 2, high strength The bonded material has high strength and can withstand a certain external force and pressure. 3. Aging resistance It has good aging resistance and can maintain the bonding effect for a long time. 4. Non-toxic The hot melt glue stick is non-toxic and harmless, safe and environmentally friendly. 5, good thermal stability It can still maintain stable adhesive performance under high temperature environment. 6. Toughness of adhesive film The adhesive film formed after bonding has good toughness and is not easy to break. In addition, the hot melt adhesive stick also has good temperature resistance, chemical resistance, corrosion resistance and other properties, its key performance indicators include softening point, hardness and melt viscosity. The softening point determines the application temperature of the hot melt glue stick, the hardness affects its operation in the hot melt glue gun, and the melt viscosity is closely related to the bonding effect.
