Hot melt adhesives are widely used in automated packaging, medical and health supplies, logistics, label tapes, automobiles, construction, household daily necessities, shoes, hats, bags and other industries. However, due to different formulas, different industries, and different application environments, in the face of many different hot melt adhesive machines and hot melt adhesives on the market, special attention should be paid when choosing hot melt adhesives. Explain your needs and applications clearly, and let the manufacturer recommend suitable hot melt adhesives. Xiamen Qixing New Materials warmly reminds everyone not to blindly choose, but to choose the correct hot melt adhesive machine and corresponding hot melt adhesive.

Notes on selection of hot melt adhesive:

1. The color requirements of glue should be different. If there is no special color requirement, it is recommended to use yellow hot melt adhesive. Generally speaking, yellow hot melt adhesives are more sticky than white ones.

2. Surface treatment of the adhered object. The surface treatment of hot melt adhesives is not as strict as other adhesives, but dust and oil on the surface of the adhesive should be properly handled to make hot melt adhesives work better.

3. Working time. Fast operation is the main feature of hot melt melters. The industry of hot melt adhesives is usually in about 15 seconds. With the wide application of modern production methods pipes, the requirements for hot melt adhesive working time are getting shorter and shorter. For example, the working time of hot melt adhesives for book binding and speaker manufacturing is 5 seconds or so.

4. Anti-temperature. Hot melt adhesives are temperature sensitive. When the temperature reaches a certain level, the hot melt adhesive begins to soften. When the temperature is lower than a certain temperature, the hot melt adhesive will become brittle. Therefore, the temperature change of the product environment must be fully considered when selecting the hot melt adhesive.

5. Stickiness. The viscosity of hot melt adhesive is divided into early viscosity and late viscosity. Only the early viscosity and late viscosity are consistent, so the hot melt and the adherend remain stable. In the production process of hot melt adhesive, it should be guaranteed to have oxidation resistance, halogen resistance, acid and alkali resistance and plasticity. The viscosity of hot melt adhesive varies according to the material to be attached, so different hot melt adhesives should be selected according to different materials.
