Hot melt adhesive: a polymer-based thermoplastic that is applied in the molten state and solidifies after cooling

Adhesive material, 100% solids at room temperature.

Polymer: such as rubber, plastic, fiber, etc.

Substances, also known as polymer materials.

Thermoplastic: The property of repeated melting and solidification under heating or cooling. Otherwise it is thermosetting.

Pressure-sensitive adhesive: that is, self-adhesive, the surface is sticky at normal temperature, and the substrate can be bonded under pressure.

Viscosity: An indicator of fluid flowability. High viscosity results in poor flowability. It is related to the nature of the fluid, temperature,

Concentration, shear speed and so on.

Softening point: The material softens when heated and approaches the temperature at which it flows.

Viscosity: or the initial tack, refers to the ability to adhere to other objects under rapid and slight pressure.

Opening time: refers to the maximum time interval from when the glue is applied until the surface can still adhere to the substrate. When the glue is open,

Only a good bonding effect can be achieved in the room. It is related to factors such as glue, temperature, substrate, and the amount of glue.
