The most commonly used type, given its cost and broad range of applications, is EVA-based adhesive (ethyl-vinyl-acetate). It provides enough strength at 30-50 °C, but its use is limited below 60-80 ºC and it has low creep resistance under load and low humidity resistance (not suitable for products for outdoor use). It is widely used in packaging applications.
A particular case of a thermoplastic adhesive is the self-adhesive group (PSA), whose main feature is its high tack, even when cold. These adhesives are also called styrene copolymer or rubber-based adhesives. They display good flexibility at low temperatures and high levels of stretching and heat resistance. They are often used in pressure-sensitive adhesive applications in which the composition remains tacky even when solidified. Normally used in labelling, non-woven, automotive and assembly applications.
