Robac Technology: Developing Nitrosamine-safe Ingredients for Rubber Manufacturing

It is well reported that traditional rubber accelerators are known to produce harmful nitrosamines during the vulcanisation of natural rubber. Nitrosamines are toxic by absorption or ingestion. They are known to cause hypersensitive reactions and can also be carcinogenic. For this reason, manufacturers prefer to use safer rubber accelerators that do not release nitrosamines or n-nitrosable compounds.  

Robinson Brothers' rubber accelerators division, Robac Technology, has continued to make safe rubber accelerators their focus for innovation. The company is pleased to announce the addition of another new nitrosamine safe rubber accelerator, Robac TINTD, to their product range.

Robac TINTD (Tetraisononylthiuramdisulfide) has been derived from a safer secondary amine, Di(3,5,5-trimethylhexyl)amine. This rubber accelerator has been specifically developed to replace traditional accelerators that produce carcinogenic N-nitrosamines during the vulcanisation process. 

Robac TINTD

• Nitrosamine safe thiuram
• Replacement for TMTD
• Replacement for TBUT

Robac TINTD is currently a development product. Scale-up studies are currently underway.
Product samples are available upon request for application testing.
