Description of key information
Zeta-potential:
The zeta-potential of MWCNT decreased with increasing pH value and the isoelectric point was found to be around pH 5 - 6 (Egger, 2010).
Impact sensitivity:
According to VDI 2263, Part 1 (Impact sensitivity) MWCNT is not impact sensitive (Heinz, 2006a).
Dust explosibility:
According to VDI 2263, Part 1 (Dust explosibility) MWCNT are dust explosible under the conditions of the modified Hartmann tube. According to ISO 6184/1 / VDI 2263/ ASTM E1226, MWCNT are classifed as St1 (low explosion violence) . The lower explosion limit is 180 mg/m3 (Heinz, 2006a; Adinex 2007, Adinex 2008b, Adinex 2010).
Dustiness:
In relation to the total air flow MWCNT showed dustiness mass fractions WR of 39.75 mg/kg drop mass and dustiness mass fractions W1 of 3626 mg/kg drop mass. This results in a classification of low for respirable dust and moderate for inhalable dust according to EN15051-B. In relation to the pari flow (according to DIN 33897-2) MWCNT showed dustiness mass fractions SA of 1.50 mg/kg drop mass and dustiness mass fraction SE of 136.83 mg/kg drop mass (IGF, 2008).
Specific surface area:
In a study, the specific surface area of MWCNT was determined using the BET method. The measurement carried out show a specific surface area of 253 m²/g (Hammer, 2006b). The specific surface area, measured by the analysis of the nitrogen adsorption isotherm according to the BET method, was determined to be in the range of 250 to 300 m²/g (Lecloux, 2011d)
Self-heating:
According to VDI 2263, Part 1, the exothermic reaction of MWCNT according to Grewer started at 291 °C. For a small amount of substance the test shows that the substance has no self-heating properties (Heinz, 2006a).
Test material is meeting the form as described in section 4.5 of the IUCLID dossier.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
