Hot melt adhesives are thermoplastic materials, which are mixed and applied in the molten state at temperatures varying from 120 to 180°C.
Hot melt adhesives are composed of three main constituents:
a high molecular weight polymer (e.g. EVA or synthetic rubber) acting as backbone and providing mainly the mechanical properties of the adhesive
a tackifying resin to provide the wetting and adhesion properties
a plasticizer, such as an oil or wax, to control mainly the viscosity of the blend and enabling the adhesive to be handled by simple machinery.
Three ExxonMobil Chemical product groups are widely used in hot melt adhesives:
Escorez hydrocarbon tackifiers
Escorene high EVA copolymers
Vector styrenic block copolymers
Escorez resins have excellent compatibility with most base polymers such as ethylene vinyl acetate, styrenic block copolymers (SIS,SBS, SEBS) and poly-alpha olefins for economic use in a variety of applications. For many hot-melt applications, Escorez resins provide both heat and viscosity stability, which plays an important role to achieve higher production with minimum machinery breakdowns and cleanings.
