High temperature cords

High-temperature cords are specialized materials designed to withstand elevated temperatures while providing various functionalities such as sealing, insulation, or reinforcement in high-temperature applications. These cords are commonly used in industries such as aerospace, automotive, manufacturing, and energy production, where exposure to extreme heat is prevalent. Here are some common types of high-temperature cords:

  1. Fiberglass Cords: Fiberglass cords are made from high-temperature-resistant glass fibers and are often used for sealing and insulation in applications such as oven doors, furnaces, and gaskets. They can withstand temperatures ranging from 500°F to over 1000°F (260°C to 538°C), depending on the specific composition and treatment.

  2. Silicone Rubber Cords: Silicone rubber cords offer excellent heat resistance and flexibility, making them suitable for sealing and gasketing applications in environments with high temperatures. They can withstand temperatures from -60°F to 500°F (-51°C to 260°C) or higher, depending on the grade and formulation.

  3. High-Temperature Ceramic Fiber Cords: Ceramic fiber cords are made from alumina-silicate fibers and offer exceptional heat resistance and thermal insulation properties. They can withstand temperatures up to 2300°F (1260°C) or higher and are commonly used in furnace door seals, expansion joint seals, and insulation applications in high-temperature equipment.

  4. High-Temperature Rope: High-temperature ropes are often made from materials such as fiberglass, ceramic fiber, or aramid fibers (e.g., Kevlar). These ropes are used for various purposes, including sealing, packing, and insulation in high-temperature environments. They can withstand temperatures ranging from a few hundred to several thousand degrees Fahrenheit, depending on the material and construction.

  5. Graphite Cords: Graphite cords offer high-temperature resistance and excellent chemical stability, making them suitable for sealing and gasketing applications in harsh environments. They can withstand temperatures up to 1000°F (537°C) or higher and are often used in aerospace, petrochemical, and automotive applications.

  6. PTFE (Polytetrafluoroethylene) Cords: PTFE cords, also known as Teflon cords, offer excellent chemical resistance and can withstand temperatures up to 500°F (260°C) or higher. They are commonly used for sealing and gasketing applications in chemical processing, food processing, and pharmaceutical industries.

When selecting a high-temperature cord for a specific application, factors such as temperature range, chemical compatibility, flexibility, and durability should be considered to ensure optimal performance and longevity. Additionally, proper installation and maintenance practices should be followed to maximize the effectiveness and safety of the cord in high-temperature environments.
