Nanomaterials (MWCNT’s) now being used in the manufacture of vehicle Tyres (Tires)

Replacing Carbon Black with MWCNT Nanomaterials in the production of Tyres

After spending several years providing the tyre manufacturing industry with consultancy, research and materials supply – we feel we are in a leading position to offer the tyre industry the support it needs to introduce nanomaterials into the production process of vehicle tyres.

In the past Carbon Black has been used as a filler – but this is not ideal for reasons of lack of functionality and its impact on the environment.

Whilst we are not in a position to reveal all the results of all our research (due to non disclosure agreement restrictions) we can offer some free guidance.

We have therefore publish a short paper explaining the benefits of using Multiwalled Carbon Nanotubes (MWCNT’s) instead of Carbon Black

How to Define a Nanomaterial

It is commonly assumed that the science community has established a definitive definition of a nanomaterial. ie “Nanomaterial’ means a natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm-100 nm.

Should this be the accepted definition?

With regulatory bodies continuing to assess to legislate on safety/toxicology of nanomaterials a realistic, real-world definition is needed, with emphasis perhaps based more on application? For example, if a material at 80nm behaves exactly the same way as it does at 200nm, then why should it be regulated differently?

The problem we all have is that different materials change their properties at differing sizes – so to define a nanomaterial purely based on its size is being questioned.

Catalogue of nanomaterials used in cosmetic products placed on the EU market

The European Commission (EC) has published a catalog of nanomaterials used in cosmetic products on the European Union (EU) market.

On February 5, 2018, the European Union Observatory for Nanomaterials (EUON) published a table linking nanomaterials listed in the catalog to their Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) registration data in the European Chemicals Agency’s (ECHA) database. See https://euon.echa.europa.eu/catalogue-of-cosmetic-ingredients

According to EUON, the linking was done by matching chemical substances in ECHA’s database through their Chemical Abstracts Service (CAS) numbers and/or with the name of the nanomaterial in the catalog. EUON notes that as the registration of nanomaterials under the Cosmetics Regulation and the registration of substances under REACH have different scopes, it is not always possible to have a perfect match. Some catalog entries are more specific in scope than the substances registered under REACH.

EUON cautions that a REACH registration may not specifically cover the nanoforms of the substances used in cosmetics.
