Heat resistant materials are extraordinary materials that can resist high temperatures and the occasional flames. They are developed through extensive research to solve extreme temperature problems faced by industrial customers around the world.
Experiments in this field involved non-asbestos materials to protect cables, hoses and other equipment from extreme temperatures, flames and molten metal splash. These materials can protect wires, pipes, cables, hoses and other equipment from burning during high temperature operations. Apart from protecting equipment, specific materials are designed to protect people from burns and exposure to heat.
There are many types of heat resistant materials serving various industries such as power generation, heavy equipment, automotive, oil, steel and marine industries. Here are the common ones used:
1. Heat resistant sealants
Sealants can resist temperatures between 550°F and 1000°F. They are used in applications that require precise sealing or bonding. Due to its unique properties, sealants are used to seal the gaps of machine sections for better resistance to high temperatures and pressure.
Sealants are also used to repair leaks in boilers, turbines, refrigerator lines, compressors and more. They do not shrink or expand, making them ideal as a seal or gasket in extreme temperature environments. There are special types of sealants that can resist flames, water, abrasion and oil.
2. Heat resistant tapes
These tapes are far from the ordinary tapes used in everyday life. Heat resistant tapes have more tensile strength and do not shrink or expand. They are used typically for wrapping wire harnesses, protecting splices and insulating coils on motors and generators. The tape’s self-bonding properties offer strong resistance to radiant heat, moisture, chemicals, electricity and corrosion.
These heat resistant tapes are manufactured in various lengths, widths, colors, thickness and weaves. They can be used in conjunction with other heat resistant materials such as fire sleeves. There are specific tapes that can resist corrosive fluids and do not generate smoke or fumes even when exposed to extreme temperature conditions.
3. Heat resistant firesleeves
Firesleeves are used to protect cables, hoses, pipes and wires. They can be installed without disconnecting cable and hoses. They are commonly applied in aerospace and industrial applications because of their ability to resist water, oil, flame and adhesives.
Firesleeves are friendly to the human touch and can protect personnel from burns even at elevated temperatures. Some types of firesleeve are made with a mirror like surface where the material reflects the heat, instead of absorbing and dissipating it through the fabric. This type of material is flexible, abrasive resistant and robust. It can also resist molten splash and flames.
4. Heat resistant ropes
Heat resistant ropes are not the same as durable ropes regularly used. These particular ropes are super tough and can be exposed to temperatures of up to 3000°F. The braided material can withstand continuous exposure to heat without burning or deteriorating in these conditions. High temperature ropes are used as a gasket or seal on boilers and industrial ovens. They are also used in applications where thermal performance is required.
5. Heat resistant fire blankets
Fire blankets come in different sizes, thickness and can be custom-made for various applications. They are used for both industrial and home applications. There are small blankets for home applications and some large ones for laboratories and industrial usage. These lightweight blankets can resist extreme high temperatures.
They can shed weld splatter and the occasional flames, as well as withstand all types of contaminants. A major benefit is that this blanket is impervious to water, moisture and hydraulic oils. Fire blankets reflect 90% of radiant heat energy. They offer unmatched abrasion resistance and tensile strength.
