What is a hot melt adhesive? TEX YEAR® Hot Melt Adhesive (HMA), also known as Hot Melt Glue is a 100% solid thermoplastic resin that liquefy when heated. When it cools, hardens on surfaces, it can bond two non-porous materials within seconds. It contains no solvents, no water, so it is eco-friendly and won’t be moldy. It is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun or kinds of applications.
Hot melt adhesives features
Hot melt adhesive provides several advantages over solvent-based adhesives. Volatile organic compounds(VOCs) are reduced or eliminated, and the drying or curing step is eliminated. Hot melt adhesive has long shelf life and usually can be disposed of without special precautions. There are various bases of HMA, including EVA, HMPSA, TPR / Rubber, APO/APAO, Polyamide and PUR.
Hot melt adhesive product forms and applications
Hot-melt adhesives are as numerous as they are versatile. In general, hot melts are applied by extruding, rolling or spraying, and the high melt viscosity makes them ideal for porous and permeable substrates. HMA are capable of bonding an array of different substrates including: rubbers, ceramics, metals, plastics, glass and wood.
For use with hobby or craft projects such as the assembly or repair of remote control foam model aircraft, and artificial floral arrangements, hot-melt sticks and hot-melt glue guns are used in the application of the adhesive. For use in industrial processes, adhesive is supplied in larger sticks and glue guns with higher melting rates.
Aside from hot melt sticks, HMA can be delivered in other formats such as granular or power hot melt blocks for bulk melt processors. Larger applications of HMA traditionally use pneumatic systems to supply adhesive.
