Pyrograf Products has declared that the United States Environmental Protection Agency (EPA) has approved the production and supply of Pyrograf-III stacked-cup carbon nanotubes, also called as carbon nanofibers, for commercial purposes in the US.
The consent order from the EPA now allows Pyrograf Products to supply its carbon nanofiber to various industries, including energy storage, polymer, automotive and aerospace, in the US.
In order to get the EPA approval, Pyrograf Products took a number of efforts that include fulfilling the reporting requirements of regional EPA, taking part in the agency’s voluntary Nanomaterials Stewardship Program, and filing two pre-manufacturing notices (PMNs). This procedure illustrates the company’s involvement towards responsible production and utilization of its products.
The patented Pyrograf-III is an inexpensive, highly graphitic stacked-cup carbon nanotube with attributes nearly equal to the theoretical values of the performance properties of graphite. It is a high–purity product and contains minimum metal concentrations and more than 99.9% of fibrous material.
According to David Burton, who serves as a General Manager at Pyrograf Products, the clients have been closely observing the status of the company’s PMNs to slate the introduction of their products based on the carbon nanofiber. The approval now allows the company to react to new fields of applications and provide regulatory assurance to its clients, he added.
