Description
1. Hot melt glue sticks are typically made from thermoplastic
polymers. The most common base polymers include ethylene - vinyl acetate
(EVA), polyamide (nylon), and polyester. EVA - based glue sticks are widely used due to their good adhesive
properties and relatively low cost. Polyamide - based glue sticks offer excellent heat resistance and
high strength, while polyester - based ones have good chemical
resistance.
2. In addition to the base polymer, various additives are
incorporated. These include tackifiers, which enhance the stickiness of the glue; plasticizers, which improve the flexibility of the adhesive; antioxidants, to prevent the glue from degrading due to oxidation; and fillers such as calcium carbonate or talc, which can adjust the
viscosity and other physical properties of the glue while also
reducing costs.
3. Hot melt glue sticks are solid at room temperature, which makes
them easy to store and handle. They are usually cylindrical in shape, with a diameter that can
vary from a few millimeters to over a centimeter, depending on the
intended use. The length of the glue sticks also varies, but a common length is
around 7 - 10 inches (18 - 25 cm).
4.When heated, hot melt glue sticks have a specific melting point
that depends on their composition. For EVA - based glue sticks, the melting point is usually around
150 - 180°F (65 - 82°C). The viscosity of the molten glue is also an important property. It determines how easily the glue can flow and spread. Glue with a lower viscosity will spread more quickly and thinly,
while glue with a higher viscosity will form a thicker layer.
5.Glue sticks come in a variety of colors, including transparent,
white, and various shades of colored glue. The color can sometimes indicate the type of polymer used or the
specific application it is designed for. For example, transparent glue sticks are often preferred for
applications where aesthetics are important, such as in crafts or
some packaging applications.
