The Uni-Barrier with Yellow Jacket is the standard barrier in all our Lead-Free profiling kits, including the wireless RF kit. A thermal barrier is the protection the SuperM.O.L.E.® Gold needs to ensure longevity through harsh environments. With piano-hinged stainless steel construction, sheathed in cool-to the touch high-temperature fabric this thermal barrier is ideal for lead-free processes. This barrier is rated to protect the SuperM.O.L.E.® Gold for 7 minutes at 200C. When used with the Yellow Jacket it is rated for 14 minutes at 200C.
