PUR hot melt adhesive primarily consists of isocyanate-terminated polyurethane prepolymer. The adhesion and toughness (elasticity) of PUR can be adjusted, and it exhibits excellent bonding strength, temperature resistance, chemical corrosion resistance, and aging resistance.
1. PUR hot melt adhesive is a solid that melts into a liquid when heated to a certain degree and is applied to the substrate. Once cured, it will not melt again.
2. Curing by moisture without drying process, saving energy and time; the adhesive layer possesses a certain degree of flexibility, hardness, and toughness.
3. Excellent initial strength, coupled with crosslinking and curing functions, results in higher ultimate bonding strength;
4. Single-component type, easy for industrial automation and mechanized operation, with high production efficiency.
5. As the product itself is solid, it is convenient for packaging, transportation, and storage.
6. It does not contain any organic solvents, with a solid content of 100%. It is non-polluting, non-toxic, and environmentally friendly.
7. Excellent heat resistance, water resistance, chemical resistance, durability, etc.
8. It is highly favored for its advantages such as simple production process, high added value, strong bonding strength, and fast speed.
9. Hot-melt adhesives exhibit stable performance, high raw material utilization, fast production speed, and high yield.
10. The equipment has the advantages of small footprint and low investment.
