Temperature resistance
Temperature resistance is a key factor when selecting materials for high temperature applications. It refers to the ability of a material to maintain its properties and shape under the influence of temperature changes. High temperature resistance is particularly important for materials used in the aerospace, automotive and chemical industries.
Materials with a high temperature resistance can withstand high temperatures without changing their mechanical or chemical properties. This property is particularly important for applications involving friction or thermal loads. Examples of materials with high temperature resistance are ceramics, metals such as titanium or stainless steel, and special plastics such as PEEK.
Temperature resistance is often determined by the material's melting point and glass transition temperature (Tg). The melting point is the temperature at which the material melts and loses its solid form. The glass transition temperature is the temperature at which the material changes from a solid to a rubbery state. Materials with high melting points and Tg values usually have a higher temperature resistance than those with lower values.
In many applications, temperature resistance is a crucial factor when selecting materials. For example, engine parts and turbine components in airplanes and cars must withstand high temperatures to ensure safe operation. Materials with high temperature resistance are also essential in the chemical industry to ensure the process flow at high temperatures and aggressive media.
Overall, temperature resistance is an important factor in material selection and has a significant impact on the reliability and performance of products and systems, especially in demanding high-temperature environments.
