Any material that has the ability to protect instruments and equipment from heat damage is called heat resistant. These heat resistant materials are used inside of ovens, on the floor of manufacturing businesses, in car parts, and in various other places.

These materials can reduce the likelihood of dangerous off-gassing caused by overheating cables, refrigeration lines, and wires. Let’s look at some of the types of heat resistant materials used in both industrial applications as well as in homes.

1. Heat Resistant Tapes

We use heat resistant tapes where normal plastic or paper tapes won’t work properly, either due to high pressure or high temperatures. These specialized tapes also have lower shrinking characteristics because of the low coefficient of expansion. Heat resistant tapes are used in high heat processes and sublimation. Different heat resistant tapes are available for different projects including ones that have a heavy coating of silicon rubber and iron oxide and are made of high bulk glass fibre.

Heat resistant tapes are made with different length, width, and colour, so you can choose from different options depending on your requirements. Heat resistant tapes can withstand temperatures up to 1650C.

2. Heat Resistant Sealants

Sealants are used to close up gaps on an industrial machine so that it can better resistant high pressure and high temperatures. Heat resistant sealant come in cement or liquid foam form. Cement sealants are mostly used to cover rough surfaces, while liquid foam sealant are used to seal machined threading and connections.

Heat resistant sealants can withstand temperatures between 157C and 816C, and can also use some of that heat to cure the seal properly. They have low shrinkage and expansion coefficient. Seals made by these materials can often also resist chemicals like brine, acids, ammonia, hydrocarbons, and mild alkalis. They can also reduce damage to machines caused by shock and vibration.

Heat resistant sealants are used in industries like heavy equipment, steel chemical, oil, power generation, marine, and more. They can be used to repair leaks present in refrigeration lines, boilers, compressors, steam turbines, condensers, heat exchangers, pressure vessels, and other thermodynamic and hydraulic systems.

3. Firesleeves

Mostly used in aerospace and industrial applications, firesleevea are silicon-coated fibreglass sleeves that work to resist temps up to 540C. They can also, depending on construction, resist adhesives, flame, water, and oil. Different products on the market are available when it comes to the type of coating inside the sleeve and the sizes offered.

Firesleeves are used in various industries to protect industrial and hydraulic hoses, wires, and cables. Firesleeves used in the aerospace industries are made of braided fibreglass to meet SAE standards, while those used in industrial applications are knitted fibreglass, which is more cost effective.

4. Fire Blankets

You may have seen fire blankets in a variety of places, including on TV or movies, or even in your home. They can put out small fires and reduce injury or damage in the event of accidents. They are made up of a sheet of fire resistant material that is meant to be draped or thrown over a fire in order to smother it. It does so by eliminating the fire’s access to oxygen.

These blankets come in a number of sizes. Small fire blankets can be used at home in the kitchen or other household applications and are made of Kevlar and/or fibreglass. They can be folded up into cylindrical storage containers and kept at-hand.

Fire blankets for industrial and laboratory usage tend to be a lot larger, and have a base of wool with flame retardant chemicals added. These are typically stored in quick-release holders which allows them to be pulled out quickly when needed.
