NBR has good resistance to mineral oils, vegetable oils, benzene/petrol, ordinary diluted acids and alkalines. An important factor in the properties of NBR is the ratio of acrylonitrile groups to butadiene groups, referred to as the ACN content.
1 lut 2024 · Commercial products such as Nitrile Butadiene Rubber (NBR), nylon, and pesticides containing amides and nitriles contribute to environmental pollution. These substances undergo gradual degradation and exhibit long-term persistence in the environment.
For example, butadiene has been listed as a toxic substance under the Canadian Environmental Protection Act. There are three tactics in use to mitigate the environmental impacts of synthetic rubbers such as NBR. The first is to reduce the emission of greenhouse gasses during production.
As leather firefighters’ gloves cannot be decontaminated regularly by wet cleaning, many Belgian firefighters wear supplementary undergloves made of nitrile butadiene rubber (NBR) to protect against the accumulation of toxicants. However, the safety of this practice has been questioned.
