ONE ADDITIVE FOR THOUSANDS OF MATERIALS
Based on the core technology
of SWCNT synthesis, OCSiAl has
developed a family of TUBALL™ –
based products for different
industries.

HAZARDOUS VS NANOMATERIAL
Decision of the Board of Appeal, June 2017:• finds that being a nanomaterial is insufficient on its
own to justify it as a potential concern;• mentions that no consistent causal links have been
established between size and hazardousproperties, yet!
• notes that the definition of nanomaterials establishes a size threshold for substances to be defined as nanomaterials.
”Being a nanomaterial is insufficient on its own to
justify a potential concern”
MORPHOLOGY & FLEXIBILITY OF TUBALL™ (SWCNT) 1/2
A long rigid biopersistent who* fiber has to be considered carcinogenic
WHO dimension, length>5 µm, diameter < 3 µm, a L:D ratio larger than 3:1
Bio-persistence: the ability of a substance to remain in the lung →bio-persistent
MORPHOLOGY & FLEXIBILITY OF TUBALL™ (SWCNT) 1/2
• Currently not classifiable as carcinogenicity to humans
• TUBALL™ does not behave like asbestosfibers …. due to non-rigidity
• No indications for any carcinogenicrisks associated to our material today
TUBALL™ ARE NOT RIGID FIBERSRigid acts like asbestos high

TUBALL™
Recent IARC publication, 2017
Mainly about the inadequate evidencein experimental animals for thecarcinogenicity of SWCNTs
HS&E ASPECTS OF TUBALL™ (SWCNT)
19 NM‘s were screened on cytotoxicityDate of publication: August 2017
Main conclusions:• SWCNT is non-cytotoxic!• All CNTs do not induce potent inflammatory
responses!• SWCNT shows a lower toxicity in certain in-
vitro experiments (Cytotoxicity in THP cells)
HS&E ASPECTS OF TUBALL™ (SWCNT)
REGISTRATIONS AND COMPLIANCE
REACH(Registration, Evaluation, Authorizationand Restriction of Chemicals)
First and only SWCNT completed(29 September, 2016)
TUBALL™ is registered under the number 01-2120130006-75-0000
Allows to commercializeup to 10 t/y in Europe
EPA(Environmental Protection Agency)
EPA consented
PMN number P-17-0257

Case studies:exposure monitoring on different handling and processes
1. R&D - handling of Tuball executed2. R&D - handling of Tuball & Tuball containing products executed
MEASUREMENT OF EXPOSURE TO INHALEDNANOPARTICLES IN THE WORKPLACE
Conclusion: CNT release was observed during the field test sampling, however CNT amounts collected were well below the NIOSH REL of 1 μg/m3 8h TWA (< 5% NIOSH REL).
3. Handling and processing of Tuball containing products Still ongoing
Conclusion: NO CNT release was observed during this type of field test sampling!
