Product List |
Pre-oxidized fiber felt, also known as pre-oxidized PAN (polyacrylonitrile) fiber felt, is a type of non-woven textile material made from pre-oxidized PAN fibers. PAN fibers are high-strength, high-modulus synthetic fibers that are commonly used in the manufacture of carbon fiber.
To create pre-oxidized fiber felt, the PAN fibers are first pre-oxidized, which involves heating the fibers in an oxygen-rich environment to convert them into a heat-stable state. The pre-oxidized fibers are then carded and needle-punched to create a non-woven felt fabric.
Pre-oxidized fiber felt has a number of desirable properties, including high temperature resistance, good thermal stability, and excellent chemical resistance. It is often used in high-temperature applications such as insulation in furnaces, boilers, and other industrial equipment. It can also be used as a filter medium in air and liquid filtration systems due to its high porosity and filtration efficiency.
