Novoloid Phenolic Fiber
The technology to produce novoloid phenolic fiber was initially developed in the late 1960’s with commercial fiber production and development by Gunei Chemical Industry Co. based in Japan.
Novoloid, or phenolic fiber, is a thermoset organic fiber produced from a phenolic novolac resin. The precursor resin is melt-spun in a solution of formaldehyde and hydrochloric acid. The reaction occurs and fibers are formed and cured. Novoloid fibers are composed of 76% carbon, 18% oxygen, and 6% hydrogen. Novoloid can also be used as a precursor to carbon fiber.
