Features Of Hot Melt Adhesives

(1) bonding quickly usually from glue to cooling adhesion, only dozens of seconds, or even a few seconds of time

(2) The bonding range is wide on many materials, and even on the recognized refractory materials (such as polyolefin! Wax paper, paper, etc.) can also be glued, especially the use of hot melt adhesive bonding joints, can withstand more than 105~106 times bending without cracking

(3) can be repeatedly heated, multiple bonding

(4) Stable performance for easy storage and transportation

(5) Low cost hot melt adhesive no solvent consumption, to avoid the existence of solvents, and so that the viscosity deformation! Dislocation and shrinkage and other ills, help to reduce costs! Improve product quality "However, hot melt adhesive also has some disadvantages " mainly heat resistance and adhesion strength is low, not suitable for use as structural adhesives " Because the melt viscosity of hot melt adhesive is generally high, the infiltration of viscous materials is poor, usually need pressurized bonding, in order to improve the bonding strength, in addition, hot melt adhesive in the use of special equipment, such as glue coating machine hot melt gun, etc. As a result, its scope of application has been limited to some extent. The physical state of hot melt adhesive changes with temperature in a certain temperature range, and the chemical properties are unchanged, which is non-toxic and tasteless, and is an environment-friendly chemical product.
