Silicon Sense, the US representative of Finnish nanodiamond manufacturer Carbodeon Ltd Oy, has become the first US-based importer of detonation nanodiamond materials to be granted registration by the US Environmental Protection Agency (EPA) to import nanodiamonds into the US for industrial purposes.

The registrations, under the Low Volume Exemption (LVE) rule, include three mono-functionalized nanodiamond grades and one multi-functionalized grade.

According to the company, nanodiamond additives can improve the performance of metal finishing, polymer thermal and mechanical compounds, polymer coatings, CMP polishing and a range of other applications.

The EPA's New Chemicals Program is aimed at minimizing potential risks to human health and the environment from new substances sold on the market. Anyone who plans to manufacture or import a new substance for commercial purposes is required, under section 5 of the Toxic Substances Control Act (TSCA), to provide the EPA with advance notice before beginning the activity. However, certain categories of new low-volume substances are exempt from full Pre-Manufacture notice (PMN) review under section 5 of the Toxic Substances Control Act (TSCA), i.e., substances manufactured at 10,000 kg/year or less.

‘Following precise environmental risk analysis using data from Carbodeon as well as invaluable inputs from a number of our US customers, the EPA has granted LVE registration for all Carbodeon proprietary nanodiamond materials currently supplied in the USA,’ said James Meriano, vice-president of Silicon Sense.
