Seller Description

This auction is for Pre-Oxidized Pan (Polyacrylonitrile) Scrap. This product is in good condition - please see notes below. We have been asked to auction this product for the seller.
Product

Processed polyacrylonitrile (PAN) fibers stabilized in a high temperature process allowing the finished product to retain their appearance, hand, and textile characteristics after exposure to open flame. This material will not burn, melt, or drip, but will rather char and self-extinguish. These fibers are 65% carbon. This is dry fiber. This is not impregnated material. This is not ?pre-preg? material (fiber already mixed with resins or treatments that would have to be removed).

Fiber Type:

Staple fiber with varied lengths with range as indicated in Auburn University lab report attached to this auction

Manufacturer

The fiber will be produced by one of two companies:

Pyron pn37 from Zoltek, see attached specs

Panox from SGL, see attached specs

Volume

Approximately 2,000 metric ton (4,400,000 lbs)

De-Compact

The preform has been run through a mill to de-compact the material to meet requirements of producer and to retain maximum specifications for new manufacturing processes. Length of de-compacted material will be:

The 3? bar cage opening produced a mean fiber length of approx. ¾?

The 6? bar cage opening produced a mean fiber length of approx. 1 ¾?

  • Elongation % - 20-32
  • Tensile Strength MPa - >210 MPa (270-330 Typical)
  • Modulus GPa - 3.3-4.9
  • Density g/cm3 - 1.355-1.385

    Packing

  • Material is baled /shrink wrapped, or bagged and will be floor loaded.
  • Bale weights are approximately 1000 - 1200 lbs.
  • Bale dimensions will maximize use of 40 foot container.
  • 40 foot container load shipping weight approximately 42,000 lbs.

    Condition

    Clean product, post industrial, direct from processing plant. Because of the process to produce the preform in a needle punching operation, there may be occasionally small broken needle tips embedded within the material. The needles are a stainless steel and the size of what remains in the preform is normally less than 1 mm in diameter. Equipment is in the present system to remove most of thismaterial including magnets and hammer milling of the preform

    Applications

    Carbon Fiber Reinforced Plastic (CFRP) products, auto fire walls, vehicle seat cushion, furniture fabrics and cushion material, fire retardant clothing, and many other applications for materials and liners requiring a material to slow or block heat orfire. Also used in the plastics industry for e-static discharge.
