Nbr Base – Technical articles

NBR based compounds designed for the production of technical articles. They usually have lower mechanic properties in comparison to SBR / NR / BR., compounds, but they show an excellent resistance to petrol-derived fluids (related to the acrylonitrile level between 18% and 50%). Range of use (temp): from -35°C to 120°C / resistant to: alcohol, water, silicone oils, motor oils, hydraulic oils – ozone resistant only if treated with specific protective agents (max 20%).
