With the continuous development of society, hot melt adhesives are increasingly inseparable from our lives. At present, the main hot melt adhesives on the market are eva type hot melt adhesives. The main component of eva hot melt adhesive is eva (ethylene-vinyl acetate polymer), which is widely used in photovoltaic and hot melt adhesive industries. However, the hot melt adhesives produced by different manufacturers, no matter the appearance (granular, rod, sheet, etc.), performance (low temperature, high temperature, medium temperature, odorless, yellow resistance), use (carton sealing, handmade, woodworking Edge banding, filter element, pearl cotton, etc.) are all different. What is the difference between the hot melt glue stick and the hot melt glue pellet in the eva type hot melt adhesive?

eva type hot melt glue stick

        The hot melt glue stick is, as the name implies, a cylindrical stick of hot melt glue. There are two international standard diameters of 7mm and 11mm. Some countries will also require 6.7mm, 6.8mm, 6.9mm, 7.0mm, 7.1mm, 7.2mm, 7.3mm, 10.7mm, 10.8mm, 10.9mm, 11.0mm, 11.1mm, 11.2mm, 11.3mm, 11.4mm, These diameters of 11.5mm can also be manufactured. Individual customers require glue sticks with special specifications such as 15mm and 14mm in diameter. Hot melt glue sticks are mainly used for handmade (paper boxes, cartons, headwear, hairpins, fake flowers, crafts, toy repair). Hot melt glue sticks need to be melted using a hot melt glue gun. Generally, a hot melt glue stick with a diameter of about 7mm needs a small glue gun of about 20w, and a hot melt glue stick with a diameter of about 11mm needs a large hot melt glue gun of more than 100w. . It can also be heated directly by a lighter. Do not touch the melted glue with your hands during use of the hot melt glue stick to avoid high temperature burns. Kindergarten children need to use it under the supervision of adults.

Hot melt glue stick production process

       How are hot melt glue sticks produced? The hot melt glue stick handwriting is heated and stirred evenly by a stirring tank, then pressurized and extruded through an extruder, and then cooled and shaped by a water tank after extrusion, and then cut by a cutter, and finally dried by drying the water and then bagged or boxed That's it.

eva type hot melt adhesive pellets

  Hot melt adhesive is a kind of hot melt adhesive with granular appearance. Mainly used for automatic hot melt glue machine or hot melt glue furnace. Because the granular hot melt adhesive allows the same weight of hot melt adhesive to have a larger surface area, it is easy to be heated and melted. The appearances made by general manufacturers are granular, cylindrical, and flake. Because the machine model is different, the appearance of the product is different. Hot melt adhesive pellets are mainly used in automated hot melt adhesive machines. Generally include pearl cotton bonding (roller hot melt glue machine), handmade (hot melt glue oven), automatic carton sealing & carton sealing, automatic filter folding line, PVC woodworking edge sealing. Due to the different components and applications of the hot-melt adhesive particles, the appearance and color of the hot-melt adhesive particles are also different. There are transparent, white, milky white, yellow transparent, yellow and other different colors. In addition, the drawing, smell, viscosity, and yellowing resistance of hot melt rubber particles are also generally concerned by consumers.

      How are hot melt adhesive pellets produced? The production of hot melt adhesive pellets is actually different from the production of hot melt adhesive sticks. A small number of cylindrical hot melt adhesive pellets are finally cut into small cylindrical pellets through the similar principle of hot melt adhesive sticks. The normal hot-melt rubber particles are heated and stirred through a heating kettle, then filtered under water to remove impurities, then pelletized under water, and finally bagged by shaking and drying. Because different manufacturers have different machines, the appearance of the hot melt adhesive particles will be a little different.

       Hot-melt glue sticks and hot-melt glue pellets are essentially the same, and both need to be heated and melted for use. Just because the environment and application used are different, the appearance will be different. Whether to use hot-melt glue pellets or hot-melt glue sticks depends on the specific application. To buy hot melt adhesive, go to a regular hot melt adhesive factory such as Weiwang Hot Melt Adhesive. Weiwang Hot Melt Adhesive has more than 20 years of hot melt adhesive production experience and is the largest hot melt adhesive manufacturer in China. The raw materials are imported high-quality raw materials and have raw material testing, and the finished hot melt adhesive has passed the SGS environmental protection testing certification. The products are sold at home and abroad and are deeply loved by customers.
