HNBR O-rings 70shore-A 80shore-A 90shore-A PTFE COATED

HNBR O-rings 70shore-A 80shore-A 90shore-A PTFE COATED

Short Description:

Hydrogenated Nitrile o-rings come from adding hydrogen to the nitrile molecular chain to make it more stable.The addition of hydrogen reduces the number of carbon-carbon double bonds, making it less reactive.It can be used in petroleum oils and fuels, R134a refrigerant gas, silicone oils and greases,ozone applications, vegetable and animal fats and fluids, water and steam (up to 300° F).Engineered Seal Products has the expertise and inventory for your hydrogenated nitrile (HNBR) o-ring applications.

For over 10 years more, BD SEALS has been the leading engineering, quality, and supply chain choice for both standard and custom sealing applications.

● Petroleum oils and fuels R134a refrigerant gas Silicone oils and greases Ozone applications, improved compression set characteristics Vegetable and animal fats Fluids Water and steam (up to 300° F)Temperature ranges will apply to the majority of media for which the material is potentially recommended.

● With some media however, the service temperature range may be significantly different.always test under acutal service conditions.

● Hydrogenated Nitrile (HNBR) o-rings, also known as Highly Saturated Nitrile (HSN), are made of a synthetic polymer that is obtained by saturating the double bonds in nitrile=s butadiene segments with hydrogen.

● This special hydrogenation process reduces many double bonds in main chains of NBR polymers.This process results in the superior heat, ozone, chemical resistance and mechanical characteristics of HNBR over standard Nitrile.HNBR o-rings are available in 70 durometer, 80 durometer, and 90 durometer.

● HNBR o-rings are preferable for use with petroleum-based oils and fuels, aliphatic hydrocarbons, vegetable oils, silicone oils and greases, ethylene glycol, water and steam (up to 300ºF), and diluted acids, bases, and salt solutions. HNBR o-rings are not preferable for use with chlorinated hydrocarbons, ketones, ethers, esters, and strong acids.

● Size:All AS-568 BS can supply what's more we can produce them according to your requirements!
