NBR Rubber:

Our silicone watch bands are made from the world's highest grade rubber: Nitrile Butadiene Rubber. NBR is used in the automotive and aeronautical industry. It is used in the nuclear industry to make protective gloves. NBR's stability at temperatures from −40 to 108 °C (−40 to 226 °F) makes it an ideal material for aeronautical applications. Nitrile butadiene is also used to produce moulded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats.

Its resilience makes NBR a useful material for disposable lab, cleaning, and examination gloves. Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength
