Nowadays, hot melt adhesives are widely used. They are commonly used for bonding and bonding of various products. The more common one is a PUR hot melt adhesive. Then the difference between this PUR hot melt adhesive and ordinary hot melt adhesives Where is it? Ordinary hot melt adhesives are a wide range of glues. PUR hot melt adhesives are one of the glues. The general hot melt adhesives are applied by heating and can be continuously heated after being laminated. They are a state reversible type. Glue, and PUR is a moisture-reactive hot melt adhesive, which is also heated and applied, but after bonding, the PUR hot melt adhesive will react with moisture in the air, and it will not be reversible after the reaction (that is, heating will not melt ), so the high temperature and low temperature resistance of PUR hot melt adhesive is better.
PUR hot melt adhesive is characterized by high cohesive strength and high bonding strength. It has good high temperature and low temperature resistance, and its performance is far superior to ordinary hot melt adhesives. The main difference between the two lies in the use of equipment, and storage environment and methods. PUR hot melt adhesives must be isolated to avoid contact with air because they will react with moisture in the air. PUR hot melt adhesives are now more popular adhesives for screen bonding and are widely used in various fields. Goel PUR hot-melt adhesives are mostly used for bonding the TP touch screens of narrow-frame mobile phones, borderless mobile phones, and flexible curved screen mobile phones with the middle frame. It has good bonding performance and can pass various test standards. It is also relatively easy to disassemble, so that the material will not be damaged and directly scrapped.

Then the difference between this PUR hot melt adhesive and ordinary hot melt adhesives Where is it? Ordinary hot melt adhesives are a wide range of glues. PUR hot melt adhesives are one type of glue. The general hot melt adhesives are heat-coated and can continue to be used after being laminated. They are a state reversible type. Glue, and PUR is a moisture-reactive hot melt adhesive, which is also heated and applied, but after bonding, the PUR hot melt adhesive will react with moisture in the air, and it will not be reversible after the reaction (that is, heating will not melt ), so the high temperature and low temperature resistance of PUR hot melt adhesive is better.
