How to Choose Heat Resistant Tubes and Cable Ties
Complete Guide by Material for 150°C to 980°C

Choosing the right material for the operating temperature is crucial. Covers Nylon, Kevlar, Glass Fiber, and Silica

We often hear concerns like, "I need a heat-resistant tube, but I don't know what temperature rating to choose." The material of heat-resistant wiring protection varies greatly depending on the operating temperature, and choosing the wrong one can lead to rapid deterioration or melting. This article explains 6 types of heat-resistant products, ranging from 150°C to 980°C, handled by Denka Electron, by material.

Basics of Material Selection by Heat Resistance

Heat-resistant wiring protection materials are selected with a guideline of "maximum operating temperature of the environment + 20-30°C margin." This is because using them at their exact heat resistance temperature will cause rapid deterioration.

Heat Resistance	Material	Product Type	Main Applications
150℃	Nylon 46	Heat-resistant cable ties	Automotive engine compartments, factory equipment, general industrial machinery
180℃	Fluororesin	Cable tie fixtures	Power equipment, around high-temperature piping, inside electronic devices
250℃	Kevlar fiber (Aramid)	Braided tubes	Industrial machinery, high-temperature wiring protection, environments requiring cut resistance
260℃	PTFE (Fluororesin)	Spiral tubes	Chemical plants, chemical environments, post-installation protection for high-temperature wiring
650℃	Glass fiber	Braided tubes	Welding, casting, furnace surroundings, ultra-high temperature machinery
980℃	Silica fiber	Braided tubes FLSL	Steelmaking, glass manufacturing, around molten metal, extreme high-temperature environments
