Choosing the best heat resistant material depends on the specific application and source of heat. Metals are durable and have high tolerance to heat, while fabrics offer flexibility. Heat resistant boards may be needed in some cases, and rubber or plastic are suitable for low temperature situations.
There are many different heat resistant materials available and choosing the best one generally depends on the specific application. Standard considerations in selecting the best heat resistant materials often depend on the source and intensity of the heat. Strong metals, fabric, cardboard, rubber and plastics all have a certain range of temperatures they are designed for. Each of these materials may be best in some situations and not as efficient in others.
In general, most heat resistant materials can withstand a certain range of heat before cracking, oxidizing or burning. The best heat resistant materials will be suited to the specific needs of an application. Metals generally have a high tolerance to heat, for example, while most plastics melt easily or otherwise deteriorate at much lower temperatures. Durability is also important, and permanent structures will often use materials that are more heat resistant than temporary ones.
Heat resistant metals are generally used in high heat situations because most metals have high melting points. Forges, for example, often use metals that can withstand temperatures higher than those used to melt the forged materials. In buildings, heat resistant metals can be used to protect structural elements in the event of a fire. Many metals can also withstand open flames, often making them ideal for building chimneys and furnaces.
When more flexibility is required, heat resistant fabric may be the best material. There are many fabrics that can withstand heat, and many of them are designed for specific temperature ranges. For example, firefighters often wear special heat-resistant materials to protect themselves from high temperatures and direct flames. Heat resistant fabric could also be used to make fire blankets or provide a layer of protection between welding equipment and nearby flammable materials.
In some cases, heat resistant board may be better than other materials. For example, a heat resistant panel may be needed to surround an oven where metal or other materials could actually increase the risk of runaway temperatures. Heat resistant board can be made using many different materials, including gypsum and asbestos, to withstand different heat ranges.
Sometimes, the best heat resistant materials might be made of rubber or plastic. The relatively low melting and burning points of these materials mean that heat resistant rubber and heat resistant plastics are often used in low temperature situations. For example, heat resistant rubber gloves might be good enough to withstand high temperature water but not direct contact with the heating elements.
