• Same day shipment on all stock heaters with postterminals or Type B leads.Hot RunnerNozzle <strong>Heaters</strong>MI Nozzle BandThe MI Band is a high performancenozzle heater constructed fromWatlow’s exclusive mineralinsulation—a material that has muchhigher thermal conductivity than themica and hard ceramic insulatorsused in conventional nozzle bandheaters.A thin layer of the “high” thermalconductive MI material is used toelectrically insulate the element wirefrom the inside diameter of theheater sheath. A thicker, “low”thermal conductivity layer backs upthe element wire, directing the heatinward towards the part that is beingheated. The result is more efficientheat transfer ... a performancesolution that lowers element wiretemperatures and increases heaterlife.Performance Capabilities• Heater operating temperatures to760°C (1400°F)• Watt densities to 35.6 W/cm 2(230 W/in 2 ) available on smalldiameter nozzle bandsFeatures and Benefits• Operating temperatures to760°C (1400°F) make it possibleto safely melt even highlyengineered resins, like Peek ,Teflon ® , Ultem ® and Zytel ® .• Higher watt densities than anyother band contribute to fasterheat-up and through-put toincrease productivity.• High thermal conductivity of MIand low mass construction givealmost instant response totemperature control.• Stainless steel design resistscontamination of plastic blowback or other free-flowingmaterials. Side folds turn to theinside diameter rather than theoutside diameter.Applications• Automotive molding• Highly engineered resinsThick LowConductivityMI BackingThin HighConductivityMI InsulationStainlessSteel SheathElement Wire inMineral InsulationCoiled or SinuatedWire ElementTeflon ® and Zytel ® are registered trademarksof E.I. du Pont de Nemours & Company.Ultem ® is a registered trademark of GeneralElectric Corporation.Peek is a trademark of Victrex plc.122
