Hot melt pressure sensitive adhesive (hmpsa) is widely used in many industries. Here are some of their characteristics and applicatioins:
1. Hot Melt Characteristics
HMPSA changes to a flowing liquid state at high temperatures to form a uniform coating on the surface. After cooling, it solidifies into a sticky glue layer.
2. Pressure Sensitivity
HMPSA is pressure-sensitive at room temperature. It can adhere to various surfaces under slight pressure without additional heating or solvent.
3. Multi-purpose Applications
HMPSA is widely used in various applications, including packaging, labels, tapes, medical supplies, automotive fields, etc.
4. Efficient Production
Due to its hot melt properties, hmpsa is widely used in automated production line. It can be quickly and efficiently applied to the materials that need to be bonded by spraying, coating or using a hot melt glue gun.
5. Environmentally Friendly Properties
The formulas of some hmpsa can be designed to be environmentally friendly and do not contain solvents, reducing the impact on the environment.
6. Adhesion Properties
HMPSA has good adhesion properties and can be attached to various surfaces, including paper, plastic, metal, etc.
7. Rapid Curing
Since it is pressure-sensitive at room temperature, the curing process of hmpsa is relatively fast, which helps to improve production efficiency.
