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.

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.
