THERMAX N990CG from Cancarb receives FDA Food Contact Notification Approval
Nordmann and Cancarb started working together back in 2007 and since then have expanded the partnership very successfully. Thermal carbon black, also known as MT carbon black, offers a range of unique properties due to its large particle size and low amount of structure. Derived from natural gas, Cancarb’s carbon blacks are characterized by a very high level of purity.

Thermax® N990 CG receives FDA-approval
Cancarb Limited recently announced that the US Food and Drug Administration (FDA) has approved the Food Contact Notification (FCN) for Thermax® N990CG, a low polycyclic aromatic hydrocarbon (PAH) replacement for Thermax® N990. FCNs are pre-submissions to the FDA for food contact substances. Cancarb is optimistic that this FDA approval will lead to new applications for Thermax® N990CG, e.g. drinking water systems, medical devices, handles for tools and sports equipment, and other PAH-sensitive rubber applications.
Replacement for Thermax® N990
Thermax® N990CG is a direct replacement for Thermax® N990, which is used in rubber membranes, expansion joints, seals, hoses, and pipes. Cancarb introduced Thermax N990CG to support customers who need to meet current and future standards for low PAH content products. To ensure compliance with European Commission Regulation (EU) No. 10/2011, the PAH content of N990CG was measured according to ASTM D8143.
Among its many other applications, Thermax® N990CG is suitable for use in EPDM gaskets that come into contact with drinking water. As Cancarb explains in a technical bulletin, N990CG meets the requirements of NSF 61, a US standard for evaluating the health effects of components in drinking water systems. EPDM seals are used in plumbing systems to prevent leaks at joints and fittings, and N990CG exhibits excellent compression set and compression relaxation performance.
Thermax® N990CG in butyl closures for pharmaceutical vials
Thermax® N990CG is also suitable for use in butyl rubber closures for pharmaceutical vials. As Cancarb shows in a technical bulletin, N990CG has acceptable levels of extractables, i.e., chemical compounds that migrate from rubber materials under certain environmental conditions.
