Nitto P-222 amber is for heavy-duty, high temperature applications where a 1-mil polyimide will not provide adequate strength or physical protection. Nitto's Kapton high performance backing ensures consistent quality. Tough backing provides the ultimate in tensile strength, tear, puncture and abrasion resistances. - Nitto P-222 is a versatile tape and is used as the primary insulation in high performance, flexible wiring boards and heater blanket assemblies. Superior physical and electrical properties are retained at higher temperatures.
