Industrial Suppliers ofSealants and Adhesives ADDING VALUE TO INDUSTRY What is Hot Melt ? • Hot melt glues are thermoplastic polymer based materials in solid form which contain no solvents or water and are non-hazardous, FDA approved and leave no risk of mould or odours in finished product. • In use, they are heated and applied molten to one surface of the parts to be glued, when the surfaces are pressed together the hot melt quickly cools to form an almost instant bond. • Hot melt Adhesives can be formulated using several different base polymers. The choice of polymer affects adhesion, temperature resistance, chemical resistance and cost.

Industrial Suppliers ofSealants and Adhesives ADDING VALUE TO INDUSTRY Formulations • Ethylene Vinyl Acetate (EVA) A commonly used polymer suitable for both packaging and product assembly formulations. It is economical and effective at service temperatures from -30°C to 80°C. • Pressure Sensitive Hot Melt Adhesives (HMPSA) Unique because they do not solidify to form a solid material, they remain permanently tacky and have the ability to wet-out substrates on contact. The bonds are formed by bringing the PSA adhesive in contact with the substrate and applying pressure. • Polyamide (PA) Polymer used to formulate adhesives with better resistance to chemicals and temperature extremes, typically -60°C to 130°C • Polypropylene (PP) Polymer used for adhesives with specific adhesion properties such as delayed setting time and often used for spray formulations. Effective at service temperatures from -30°C to 110°C • Polyurethane (PUR) Polyurethane Reactive Hot melt initially sets like a conventional hot melt by losing heat and solidifying. Following this, the PUR absorbs a small amount of moisture from the surrounding materials or atmosphere and cross links. This is a permanent chemical change that takes several days which increases both heat and chemical resistance. Since a small amount of moisture is required for this reaction to take place it is better if at least one substrate is porous.
