Impeder Casings
Epoxy:
180°C max (365°F). Epoxy (G10 or G11) is a high strength epoxy resin that is reinforced with glass fiber. These epoxy casings exhibit outstanding wear resistance, ensuring they maintain their structural integrity and performance even in demanding conditions.
Silicone:
210°C max (410°F). Silicon (or G7) casings are composed of high temperature resin and silica. Silicon casings are primarily used with return flow impeders. Silicone casings are ideal for extreme heat applications due to their exceptional thermal stability.
Magnatube:
210°C max (410°F). Magnatube is a newly developed proprietary ferrite impregnated casing that, in initial tests, have shown an average of at least 24% higher permeability ratings than the leading competitor’s ferrite casing. In addition, the max working temperature of the Magnatube™ casing is 210°C, which is the same as Silicon. In some cases, the addition of ferrite to the casing can increase welding speeds by as much as 40% when running smaller diameters.
Reinforced Epoxy:
220°C max (428°F). The reinforced epoxy is a G11 epoxy reinforced for higher temperature capabilities, with characteristics similar to our epoxy impeders but able to work up to 220°C.
Duraguard:
327ºC max (621ºF). Duraguard is the newest style of impeder casing. Made from extruded Teflon, Duraguard gives increased wear resistance and strength for a longer lasting casing, which make it suitable for demanding applications. At a working temp of 327ºC, Duraguard could very well be the hottest running casing on the market.
