OTHER USES:

MSDS: Yes Label: No

Gen Eqpt: protecting gloves (e.g. nitrile rubber, thickness greater than 0.35 mm) / chemical goggles or safety glasses Respirator: suitable respiratory equipment with High Efficiency Dust Cartridge (at least a P2 filter) when directly exposed or handling the powder Health Effects: contact with eyes may cause irritation due to abrasive action of the dust; not expected to cause prolonged or significant eye irritation / skin contact: no known hazards, but may be mildly irritating to the skin; it is not expected to be absorbed through the intact skin / inhalation of the dust from this material may cause respiratory irritation / ingestion: no known hazards; not expected to be harmful if swallowed / acute and chronic health effects: high concentration of dusts may be irritating to eyes, skin, mucous membranes and respiratory tract; no applicable chronic information at this moment, but none of the components is known to be a carcinogen or a suspected carcinogen

TLV/PEL: Carbon nanotubes 2.5 ug/m^3 LOAEC (Low Observed Adverse Effect Concentration) Nanocyl recommends a LOAEC of 0.1 mg/m^3 and applies a safety factor of 40 to achieve an air threshold of 2.5 ug/m^3.

CRSS : Chemical Name: Multi-walled carbon nanotubes S-H20: 0.000001 g/L @

VP: 1.0E-6 torr @MW: %<500 %<1000 Physical State and Misc CRSS Info: Neat: Solid Mfg: NK: Import Proc/Form: NK End Use: Solid: LVE material entrained within polymer. The molecular weight is variable and depends on the size of the nanotube. It is expected to be much greater than 100,000 g/mole. The submitter claims that there are two kinds of nanotubes, short tangled nanotubes and long rigid nanotubes. This LVE is for the short tangled kind of carbon nanotubes. Submitted Data: Burns before melting; Insoluble in water; Average Diameter = 9.5 nm; Average Length = 1.5 μm; Surface Area = 250-300 m^2/g; Agglomerate Particle Size: 4.7% < 0.1mm, 58.5% 0.1-0.5 mm, 33.9% 0.5-1 mm, 2. 9% 1-2 mm, 0% > 2mm by sieves, 10-2000 μm by light scattering at 1 bar, 10-600 μm by light scattering at 4 bar; Stable up to 480 °C in an oxidative atmosphere; Explodability: Kst = 42 bar*m/sec (VDI). Estimated Data: BP > 400 °C (High MW); VP < 0.000001 torr (High MW); WS < 0.000001 g/L (High MW).
