HNBR o rings

Manufacturer of HNBR rubber orings

They are designed to increase the thermal resistance of ordinary NBR orings.  Their improved version is  hnbr orings, which combine manyadvantages, thanks to which they find a wide range of applications – especially dynamic ones. They are resistant to mechanical damage (e.g. abrasion), as well as to engine, diesel and bio-oils,mineral-based hydraulic fluids and vegetable and animal fats. The so-called green orings are distinguished by thermal stability, which means that they are insensitive to very large temperature scales: from -30 °C to +150 °C.
The product comes in different sizes. It will be effective wherever there is contact with liquids to which it is resistant, and where mechanical forces can act on it damaging weaker orings. Hydraulic fluids such as HFA, HFB and HFC, aliphatic hydrocarbons, ozone or weather conditions are also not able to destroy HNBR orings.  All thanks to the production process aimed at obtaining a product of high quality and durability.

HNBR O-ring from the manufacturer of rubber products

Material - HNBR rubber

The material from which HNBR  orings are made is butadiene-acrylitrile rubber.  It was created by modifying nitrile rubber (NBR) by  hydrogenation.
Its use is indicated at temperatures from -30°C to +150°C.

Gaskets made of HNBR are resistant to various types of lubricants, fats, oils from vegetable and animal to mineral, but the driving force should mention the harmful effects on such oil and motor grease seals, as well as chlorinated hydrocarbons, ketones or glycol-based liquids. Another advantage is the low susceptibility to diluted acids and aces, as well as factors such as hydraulic fluids, gasoline or propane, butane and even ozone.

Due to its good mechanical and physical properties, that is, high resistance to abrasion, stretching, loads or deformation has been used in both static and dynamic systems. It is used, among other things, in hydraulic systems such as pumps, motors or pneumatic systems such as elevators, feeders, brakes.
