Hot melt adhesive particles are solid adhesives that are heated above their melting point before being applied to a substrate. According to the desired application, hot melt adhesive has various appearances and textures. They do not require a curing or drying period as they quickly solidify when cooled to the freezing point. Therefore, hot melt adhesive usually appears on automated production lines that rely on rapid bonding formation.
As a manufacturer of hot melt adhesive granules, Guangzhou Sunlife has invested in manufacturing and extrusion equipment to ensure that our adhesives not only have a clean appearance, but are also the cleanest products available for your application equipment.
Choosing the correctHot melt adhesiveis important because the adhesive required to complete a task can vary greatly. The common hot melt adhesives used by hot melt adhesive suppliers and technology adhesive manufacturers are EVA (ethylene vinyl acetate), metallocene, polyethylene, APAO (amorphous poly alpha olefin), and PSA (pressure-sensitive adhesive).
EVA: One of the ancient hot melt adhesive application technologies. Because of this, there are a large number of raw materials available for preparation. EVA hot melt adhesive is made from petroleum as raw material and has a highly competitive price.
Metallocene: The latest hot melt adhesive technology introduced for the packaging market. Although not as good as based on EVA It is as versatile as hot melt adhesive, but it can provide heat and cold resistance in one formula. This technology will provide a carbon free environment for dispensing equipment.
APAO: When EVA hot melt adhesive cannot meet all requirements, APAO hot melt adhesive is usually used. APAO Technology will provide extended opening hours and extreme temperature conditions. Usually used for automotive applications and professional assembly applications.
PSA: Based on rubber technology, it can provide unlimited residual viscosity. Label inventory manufacturing, automotive assembly, high-speed bottle labeling, and customized applications have become the forefront of this technology.
Direct answer: The reason for the broken glue when flipping pages in the adhesive book is that the glue layer has not penetrated into the back of the book and the glue layer is brittle. The solution needs to start from four aspects – milling and slotting should be in place, the temperature and amount […]

The principle of handling is simple: mild adhesion can be spread out and left to air, and after being dispersed, it can be used as usual; If there is obvious moisture absorption, whitening or […]
