What should you pay attention to when choosing hot-melt adhesive?

The adhesion of hot-melt adhesives is characterized by both early-stage and long-term tack. Only when these two types of tack are consistent can the adhesive maintain stable bonding with the substrate. During production, hot-melt adhesives should exhibit resistance to oxidation, halogens, acids and bases, as well as good plasticizing properties. Moreover, since different substrates exhibit varying degrees of surface energy and chemical compatibility, the choice of hot-melt adhesive must be tailored to the specific material being bonded.

The principle and structure of TPE/TPU products that change color in response to temperature at 31°C

Thermochromic pigments are prepared from electron-transfer-type organic compound systems. Electron-transfer-type organic compounds are a class of organic chromophoric systems characterized by a unique chemical structure. At a specific temperature, electron transfer causes changes in the molecular structure of these organic compounds, thereby triggering color transitions.

Before selecting a hot-melt adhesive machine, choose a high-quality TPU hot-melt adhesive.

Hot-melt glue guns do not have particularly stringent requirements for hot-melt adhesives; virtually any type of hot-melt adhesive can be used. However, to achieve optimal bonding performance, it is essential to select the appropriate hot-melt glue gun and adhesive.

“The claim that ‘environmental regulations are driving up raw material prices’ is a false premise.”

Since its launch at the end of 2015, the central environmental inspection campaign has adopted a zero-tolerance, iron‑fisted approach to pollution, driven by the determination to tackle deep‑rooted problems and the courage to make tough, painful reforms. In just two years, it has covered all 31 provinces, autonomous regions, and municipalities directly under the central government, resulting in accountability measures against more than 15,000 individuals. The tangible results in curbing pollution have been widely recognized and highly praised by the public. At the same time, however, claims that “environmental inspections have triggered a wave of price hikes” have gained considerable traction.
