NBR (THNBR145580)

NBR is selected primarily for its excellent Oil and Chemical resistance and good mechanical performance at moderately high temperatures, and is widely used in Automotive, Oil & Gas, Power Plant and Engineering Industries for Seals and Gaskets in applications where hydrocarbons, chemicals and acids are present. In the automotive area, NBR is used in water handling applications and in fuel and oil handling hose, seals and grommets. With a temperature range of –40 to +125 degree celcius, NBR materials can withstand all automotive applications. This form of synthetic rubber because of its resilience is the perfect material for power plant industry uses, for many sealing applications such as airlock doors, hatches, pool gates, drywell heads, vibration dampening and others
