- Yields lightweight, hard filling compouds
- For epoxy, polyester, and vinyl ester resins
Milled carbon is made from recycled fibres. The carbon fibres used therefore are equipped largely with PU-sizing. Most of the sizing evaporates due heat generated at the milling process though. When dry the milled fibres form fibre balls, which dissolve and spread out evenly in resin.
Carbon fibres content: 100 % (99 %)
including ex-PAN fibres: > 90 %

Monofilament diameter: 7 µm ± 2
Volume resistivity (average volume resistivity of n (n > 1000) monofilaments): 15 µΩm (max. 20)
Tensile strength: 3500 MPa (3000)
Elongation at break: 1.5 % (1,2)

Median length: 200 µm ± 30
Manufacture of electrically conductive coatings and adhesives, reinforcement of moulding and fillings.
*Average values obtained from technical data sheets of producers of ex-PAN ‘‘high strength’’ fibres that we use in our mixture for more than 90 %. The ≤ 10 % remaining are ‘‘high modulus’’ fibres from the same producers, i.e. TORAYCA®, TOHO-TENAX, CYTEC... All these values are given as a rough guide.
