Product Description

    Pre-oxidized Pan Yarn was made by Pre-Oxidized Pan which is an oxidized polyacrylonitrile (PAN) fiber which does not burn, melt, soften or drip. As an internationally recognized industry standard for non-flammable textile fibers, Pre-Oxidized Pan can be used in many different fields as an effective protection against fire and heat. The LOI value of Pre-Oxidized Pan is above 45%, is considerably higher than that of other fibers and corresponds to combustion class S-a according to DIN 66083.

    Pre-oxidized Pan Yarn was made by pre-oxidized Pan fiber with ring spun process. Limit oxygen index is above 45%, with excellent thermal stability, no melting no drip , no softening shrinkage, it has excellent flame retardant, high temperature resistance and heat insulation functions.

    We choose the A grade pre-oxidized Pan fiber to produce the preox yarn, such as SGL panox fiber, Zoltek OX fiber.
