Hnbr Vs Nbr Properties

Hnbr Vs Nbr Properties. The differences are as follows: Fkm sealing ring heat resistance characteristics and silica gel, can be said to be the stage of vulcanized rubber polyurethane elastomer stronger, the basic type of fluorine rubber.

There are 6 material properties with values for both materials. Hnbr, like nitrile, increasing the acrylonitrile content increase resistance to heat and petroleum based oils and fuels, but decreases the low temperature performance. The most commonly used nbr polymers are those with a 33% to 38% acn content.

Hnbr exhibits excellent heat, ozone and chemical resistance properties through the introduction of saturated bonds into the main chain. Good compatibility with other types of polymers and materials.

In particular, abrasion resistance, combined with good mechanical properties at elevated temperatures, plus excellent resistance to many chemically aggressive technical oils. Both nbr rubber and hnbr rubber are thermoset elastomers (rubber).

The Differences Are As Follows:

Tensile strength and abrasion resistance than standard nitrile (nbr). Properties with values for just one material (12, in this case) are not shown. They have rather better oil and chemical resistance than nitrile rubber and can withstand much higher temperatures.

Hnbr Shows Good Mechanical Properties.

Highly saturated nitrile (hsn) temperature range: Hnbrs have better oil and chemical resistance than nitrile rubbers and can also withstand higher temperatures. These double bonds are also prone to chemical attack, thermal degradation and oxidation.

Hnbr Rubber Compound Obtained By Hydrogenating Nbr Nitrile Rubber , Hnbr Offers Outstanding Physical Properties.

The nbr and fkm are the commen bearing sealing ring material. Also an excellent choice for automotive refrigerant service. The hydrogenating process saturates the polymeric chain with accompanying improvements to the ozone, heat and aging resistance of the elastomer and improves overall mechanical properties.

High Rdb Increases Crosslinking Density 4.

The difference between nbr seal and fkm seal of the bearing. In particular, abrasion resistance, combined with good mechanical properties at elevated temperatures, plus excellent resistance to many chemically aggressive technical oils. Hnbr rubber belongs to the thermoset elastomers (rubber) classification, while ptfe belongs to the thermoplastics.

There Are 6 Material Properties With Values For Both Materials.

In addition to these properties, nitrile rubber demonstrates: Hnbr, like nitrile, increasing the acrylonitrile content increase resistance to heat and petroleum based oils and fuels, but decreases the low temperature performance. Hnbr is a hydrogenated version of nbr (nitrile) rubber.
