Carton closure hot-melt packaging adhesives using ethylene vinyl acetate (EVA) polymer systems have been used for decades due to their availability, formulation latitude and performance attributes. Packaging adhesive formulations typically contain polymer, tackifier resin and wax.
QUESTION: We want to bond steel to foamed polystyrene in large bond areas, and we want to use a cost-effective adhesive that doesn’t take long to dry. Is a hot melt the way to go?
A new generation of polyolefins with valuable properties has been introduced.
Polyolefin-based, hot-melt adhesives have proven their advantages in various fields of adhesive applications in recent decades. In the last 10 years, a new generation of polyolefins have been introduced, showing new and value-adding properties for the hot-melt adhesive customer.
Concert™ series temperature controllers reportedly provide an easy, economical way to increase application flexibility and capacity of material melters.
This company’s automotive group has introduced TECHNOMELT XPO 1050, a polyolefin-based hot melt that can reportedly bond a variety of interior-related substrates without the need for pretreatment of the plastic surface.
This company has introduced Swift®lock 2U232-3N, a UL 10C fire-rated component status adhesive designed to help door manufacturers improve production while meeting industry certification and fire rating requirements.
Today’s hot-melt formulators face many challenges, including variations in the availability of raw material supply and the pressure to reduce formulation costs. High-efficiency polymers can help formulators by reducing formulation viscosity or increasing formulation flexibility, which allows for the exchange of resin or oil for polymers.
