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.
September 4, 2013
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.
A new type of acrylic copolymer has been developed that features block structures and controlled functional group placement due to a controlled radical polymerization process.
Acrylic polymers are widely used in pressure-sensitive adhesive (PSA) applications in the form of emulsion, solvent or radiation-cured systems. They combine good UV resistance, transparency, tailored tack, and stiffness due to a large choice of acrylic and methacrylic comonomers.
