HNBR O-Rings

Item:OR-HNBR
PDF:no !pfd

Specification:

Description:In comparison with NBR O-Rings, HNBR O-Rings has better abrasion resistance, tear resistance, high-temperature properties and resistance to chemical attacks. It can be used in ozone applications, R134a refrigerant gas, petroleum oils and fuels, water and steam, silicone oils and greases, vegetable and animal fats and fluids.

HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat,oil and chemicals.HNBR has better heat resistance,oxidation resistance,tensile strength and abrasion resistance than standard nitrile (NBR).Due to its excellent cost-performance balance and use in highly demanding applications such as automotive,industrial applications which require high performance.

Just like NBR,there are different levels of Acrylonitrile (ACN) content in different HNBR polymers.The ACN content can be varied from 18% to 50%.Lower ACN content gives better low-temperature properties but lesser resistance to fuels and polar lubricants.Higher ACN content gives inferior low-temperature properties but improves fuels and polar lubricants resistance.

HNBR are specifically designed to provide superior temperature and fuel resistance compared to traditional NBR materials.HBNR o-rings also feature excellent abrasion,compression set resistance and has excellent resistance to oils and chemicals.The HNBR O-ring has been developed to meet higher temperatures than standard NBR while retaining resistance to petroleum based oils.The HNBR O-rings has a temperature range from -40C to +150C and fills the gap where high temperature conditions require high tensile strength while maintaining excellent resistance to oils and chemicals,making them a reliable o-ring in a wide range of tough applications.

In fact,due to superior oil and temperature resistance,Highly Saturated Nitrile can sometimes be substituted for more costly fluorocarbon rubber.HNBR O-rings is frequently used in automotive air conditioning systems employing R-134a refrigerants.It exhibits good resistance to petroleum based oils,compression set and a variety of Freons.Its an excellent choice for automotive refrigerant service.

HNBR O-Rings Material Characteristics:
