Vertical Integration
Our comprehensive vertical integration of the manufacturing process uniquely enables Grafil Inc., together with our parent company Mitsubishi Rayon (MRC), to fully control every step of the carbon fiber production process.
Our proprietary carbon fiber process begins in a world scale synthetic fibers plant and concludes in highly sophisticated carbonization facilities in the US and Japan.
We start by combining commodity raw materials in a series of chemical reactions to produce acrylonitrile, which is then polymerized to form polyacrylonitrile (PAN). A solution of this PAN is then spun into a precursor. This critical step ensures the maximum potential quality and consistency of the carbon fiber.
This potential is realized during the carbonization process, a precisely controlled pyrolysis of the PAN precursor to form carbon fibers.
