Do you know what are the most widely used types of hot melt glue sticks? Now let me tell you about it! The demand for hot melt glue sticks is constantly being innovated and developed. The existing hot-melt glue stick should be modified, and the existing hot-melt glue stick should be modified by mixing, chemical reaction and other methods to improve the characteristics of the hot-melt glue stick.
1. It is a hot-melt glue stick with acrylic as the main body. The soft monomer is butyl acrylate, the soft is ethyloctyl acrylate, and the hard monomer is methyl methacrylate, styrene, acrylonitrile, etc.
2. It is a hot-melt glue stick with butadiene as the main body, and the hard monomer is styrene (styrene-butadiene emulsion), acrylonitrile (nitrile emulsion), and other polymers are compounded to add film strength.
3. It is a polyurethane hot-melt glue stick, which is a polymer formed by polymerization of polyisocyanate compounds and polyether or polyester rich in vivid hydrogen atoms. If polymerized with polyester is called polyester polyurethane, the hot-melt glue stick has good light resistance and heat resistance, and has good elasticity, but is not resistant to hydrolysis, and the polyurethane hot-melt glue stick is suitable for printing knitted fabrics because of its good elasticity and soft and non-sticky, and will not be like the acrylic hot-melt glue stick that can absorb dust in the air, and the dyeing fastness is good.
