SIRQUEIRA, Alex S. et al. Nitrigreen the ecological rubber. Polímeros [online]. 2009, vol.19, n.1, pp.10-13. ISSN 1678-5169.  https://doi.org/10.1590/S0104-14282009000100007.

New vegetable oil pre-plasticized rubbers (Nitrigreen) with 33% of acrilonitrile were especially developed by Nitriflex to supply the rubber market necessities. Nitrigreen complies with European regulation 2005/84/EC as it uses a plasticizer from renewable source. This rubber has superior effect in the Mooney viscosity reduction compared with usual plasticizer such as phthalates. In addition to the ease of processing, Nitigreen is compatible with vulcanization additives and may be used in low hardness products, including toys, cylinders and technical parts. This new pre-plasticized nitrile rubber with 50 phr of plasticizer has excellent processability, low consumption of energy, and facilitates incorporation of additives, especially reinforcing loadings such as carbon black. The mechanical properties of this rubber are slightly superior to those of a rubber containing DOP.

Palavras-chave : Nitrile rubber; plasticizer; vegetable oil; vulcanization; DOP.
