Hot melt adhesive is a kind of adhesive with strong plasticity, and this adhesive can be bonded with a variety of substances, and its properties can change with the change of temperature. After curing, it has strong adhesion and strong bonding strength. Therefore, many industries will use this adhesive. If this adhesive is for ordinary household use, the quality is not important. If it is used in the industrial field, it is necessary to pay attention to quality, so how to judge the quality of hot melt adhesives? Let's learn with Barmarosa!


1. The composition of hot melt adhesive can be detected and analyzed under professional instruments, so that accurate data can be obtained.


Second, it can also be observed on the appearance. If the hot melt adhesive is inconsistent and the workmanship is relatively rough, then the quality is worrying.


3. The tensile strength can be tested after the hot melt adhesive is melted. If the tensile strength is poor, the hot melt adhesive is unqualified.

4. After the hot melt adhesive is melted, observe whether there is powdery substance. If there is powdery substance, it means that there are many fillers and poor bonding performance.


5. The hot melt adhesive with good quality has temperature resistance. The hot melt adhesive can be tested in an environment above zero or 40 degrees. If there is brittle cracking and softness, it means that the quality of the adhesive is not good.


At present, only good quality hot melt adhesive can be used in the field of industrial manufacturing, and the temperature resistance and flame retardant performance can be guaranteed. At present, the products of big brands that can meet this quality requirement are widely used, and can be used in new energy, military industry , medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
