These compounds are available in many different packages. The most used varieties are the pre-cut plate and the continuous rubber plate (powder or liquid batchoff antiadhesive material) for the fourth group: NBR /NBR-PVC based compounds designed for the production of technical articles. Their mechanic properties are usually good but lower in comparison to SBR / NR / BR compounds; 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%).
