About HT800

HT800 is a type of closed-cell silicone sponge material that is manufactured by Rogers Corporation, a global leader in engineered materials for various industries. HT800 is known for its excellent compression set resistance, high-temperature resistance, and good electrical insulation properties.

HT800 silicone sponge is typically used in various applications, such as gasketing, cushioning, and thermal insulation, where a combination of high-temperature resistance and compression set resistance is required. It is also used in electronic equipment, automotive applications, and aerospace industries.

HT800 silicone sponge material is available in various thicknesses and densities, making it suitable for a wide range of applications. It can withstand temperatures ranging from -70°C to 200°C (-94°F to 392°F) and has a compression deflection range of 5-18 psi.

Overall, HT800 silicone sponge is a high-performance material that offers excellent temperature and compression resistance properties, making it suitable for various industrial applications.

The benefits of HT800 silicone sponge include:

  • Excellent compression set resistance: HT800 has a low compression set, which means it can retain its original shape even after prolonged compression. This makes it an ideal material for use in gasketing, sealing, and cushioning applications.
  • High-temperature resistance: HT800 can withstand high temperatures of up to 200°C (392°F) without losing its physical properties, making it suitable for use in applications where exposure to high temperatures is a concern.
  • Good electrical insulation properties: HT800 has good electrical insulation properties, making it ideal for use in electronic equipment and other applications where electrical insulation is critical.
  • Good chemical resistance: HT800 is resistant to many chemicals and solvents, making it suitable for use in applications where exposure to harsh chemicals is a concern.
  • Good dimensional stability: HT800 has excellent dimensional stability, which means it maintains its shape and size even after prolonged exposure to temperature changes, humidity, and other environmental factors.
  • Easy to fabricate: HT800 is easy to cut, die-cut, and mold into various shapes and sizes, making it suitable for custom applications.

HT800 silicone sponge is used in a wide range of industrial applications, including:

  • Gasketing and sealing: HT800 is commonly used as a gasket or sealing material in applications where a high-temperature, compression-resistant material is required. This includes sealing applications in the automotive, aerospace, and industrial sectors.
  • Cushioning and vibration dampening: The excellent compression set resistance of HT800 makes it an ideal material for cushioning and vibration dampening applications. It is used in equipment mounting and transport applications to protect delicate equipment from damage during transport or operation.
  • Thermal insulation: HT800 has excellent thermal insulation properties and is used as an insulating material in a range of applications. This includes insulation for industrial equipment and appliances, as well as thermal barriers for high-temperature pipes and ducts.
  • Electronic equipment: HT800 is commonly used in electronic equipment, such as computers, servers, and telecommunications equipment, as a thermal interface material to transfer heat away from sensitive components.
  • Automotive industry: HT800 is used in a range of automotive applications, including as a gasket or sealant material, vibration dampener, and thermal insulator.
  • Aerospace industry: HT800 is used in the aerospace industry as a gasket or sealant material, thermal insulator, and vibration dampener.

Overall, the benefits of HT800 silicone sponge make it an ideal material for various industrial applications, including gasketing, sealing, cushioning, thermal insulation, and electronic equipment.
