PV (kg/yr): Import Only

SUBMITTER: Nanocyl Corporation

USE: Plastics additive to improve electrical, thermal and/or

mechanical properties.

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
