High temperature resistant wire can usually be understood as ordinary flame retardant and low halogen and low smoke flame retardant. The working temperature requirement is greater than 90 °C. The main reason is the difference between additives and filler materials. What bromine antimony series, phosphorus nitrogen series, magnesium hydroxide and Aluminum hydroxide has a higher technical threshold.

High-temperature wires are divided into fluoroplastic insulated and heat-resistant wires and cables, silicon rubber insulated and sheathed wires and cables, mica-wound color and heat-resistant wires and cables, and electric heating tapes. Products are widely used in aviation, metallurgy, chemical, petroleum, electric power, automotive, electronics, machinery and household appliances industries.
