Results for tag: "Polyurethane Hot Melt Adhesives"

Polyurethane Hot Melt Adhesives (PUHMA) are a type of polyurethane adhesive that is applied in a hot, molten state and then cooled to form a strong bond. PUHMA are used in a variety of industries, including automotive, construction, furniture, and packaging. They are known for their superior strength, flexibility, and resistance to temperature and moisture. PUHMA are also highly resistant to chemicals, making them ideal for use in harsh environments. PUHMA are typically composed of polyols, isocyanates, and other additives. The polyols provide the adhesive with its strength and flexibility, while the isocyanates provide the adhesive with its heat resistance and chemical resistance. The additives are used to modify the properties of the adhesive, such as its viscosity, curing time, and adhesion. PUHMA are available in a variety of forms, including pellets, granules, and liquids. They are also available in a range of colors, allowing for a wide range of applications. Some companies in the PUHMA market include Henkel, 3M, Sika, Bostik, and Dow. Show Less Read more
