Nordson EFD introduces Unity™ HiTemp™ syringe barrels. These disposable 30-cc barrels reduce the downtime and maintenance costs often associated with aluminum barrels commonly used in the pneumatic dispensing of hot melt adhesives, according to the vendor.
The barrels are available in two models: a standard HiTemp syringe barrel that withstands 257° F for eight hours at up to 87 psi (6 bar) and an Extreme HiTemp syringe barrel that withstands 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 as well as other standard industry hot melt dispensers.
