HNBR (Hydrogenated Nitrile, Buna-N)
HNBR Seals & O-Rings offer improved performance and higher temperature capability over traditional NBR.
Hydrogenated Nitrile is the addition of hydrogen to the polymers chain of NBR (Nitrile Buna-N).
Competitive lead times & pricing from Lanson Polymers allied with our vast experience in the design & supply of critical seals & components into a variety of markets will allow you to specify the optimum solution for your application.
A wide variety of seals and components can be manufactured using HNBR Materials including:
O-Rings, T-Seals, L-Seals and Cap Seals amongst others.
