Nordson has introduced 30cc disposable Unity HiTemp syringe barrels which reduce the downtime and maintenance costs often associated with aluminum barrels commonly used in the pneumatic dispensing of hot melt adhesives.
The barrels are available in two models - a standard HiTemp syringe barrel that withstands 125° C (257° F) for eight hours at up to 87 psi (6 bar) and an Extreme HiTemp syringe barrel that withstands 180° C (356° F) for eight hours at up to 100 psi (7 bar).
The standard HiTemp barrels can be used with all hot melt adhesives, including moisture cure polyurethanes (PURs) and silyl modified polymers (SMPs). The Extreme HiTemp barrels can be used with polyamides and other types of hot melts, and block UV light between 200 and 500 nm. Both models are compatible with all Nordson EFD Optimum metal dispense tips, adapters, and end caps. An Extreme HiTemp tip cap is available for applications above 125° C.
All Unity syringe barrels are compatible with Nordson's Unity IC Series and Unity PURJet 30 dispensing systems, and other standard industry hot melt dispensers. "Engineered with materials that withstand high temperatures, Nordson EFD's Unity HiTemp disposable syringe barrels for hot melt dispensing offer a better cost of ownership with less adhesive waste than current available options," said Brian Dodier, product manager, Nordson EFD.
