Teflon, also known as PTFE (polytetrafluoroethylene), is a synthetic material known for its high temperature resistance, chemical resistance, and excellent electrical insulation properties. Teflon wire is a type of electrical wire that is coated with a layer of Teflon insulation. Teflon wire is commonly used in applications where high heat, harsh chemicals, and electrical insulation are critical, such as in aerospace, automotive, and industrial equipment.

Teflon SS wire, on the other hand, is a type of Teflon wire that is also coated with a layer of stainless steel braiding. The stainless steel braiding provides an additional layer of protection against physical damage, abrasion, and EMI/RFI interference. Teflon SS wire is commonly used in applications where high temperature, chemicals, and mechanical durability are critical, such as in military, aerospace, and industrial equipment.

Overall, Teflon SS wire is a reliable choice for high-performance applications where extreme temperatures, harsh chemicals, and mechanical durability are critical, and where EMI/RFI interference needs to be minimized. The Teflon insulation provides excellent electrical insulation properties, while the stainless steel braiding provides additional protection against physical damage and EMI/RFI interference. Teflon SS wire is more expensive than other types of wire insulation, such as PVC or rubber, but its superior properties make it a preferred choice for many high-end applications.
