Difference Between Natural Rubber and Nitrile Rubber

The main advantage of NBR over natural rubber is NBR’s ability to trap and retain gas. Synthetic nitrile rubber holds nitrogen bubbles within its structure making it the perfect choice for closed cell sponge appliions. Natural rubber allows these bubbles to pass right through the cell wall, making it the weakest material for this use.

Nitrile vs. Neoprene - What''s the Difference? | Rubber …

07/07/2019· The differences don’t end there. Nitrile rubber has poor flame resistance. By contrast, neoprene provides very good-to-excellent resistance against the spread of flame. Nitrile is attacked by sunlight, ozone, and weather, but neoprene provides reliable resistance against these environmental conditions. Yet neither rubber resists aromatics or

Nitrile rubber - Wikipedia

Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. Trade names include Perbunan, Nipol, Krynac and Europrene.This rubber is unusual in being resistant to oil, fuel, and other chemicals. NBR is used in the automotive and aeronautical industry to make fuel and oil …
