Category:Industry news Source:This station Datetime:2023-10-05 15:45:00 Hits:267

As we all know, the O-ring is made of a variety of rubber materials, and the rubber material of Haide Paike is fully covered. The commonly used O-ring materials are nitrile butadiene rubber (NBR), hydrogenated nitrile butadiene rubber (HNBR), EPDM, fluororubber (FKM/FPM), fluororubber (F-SIL/FVMQ), silicone rubber (SIL/VMQ), rubber. Neoprene rubber (CR), perflurane rubber (FFKM), tetrapropyl fluoro rubber (AFLAS), acrylic rubber (ACM) and so on. Faced with so many materials, how do we choose the right material O-ring? We share with you the advantages and disadvantages of different materials of O-rings, hoping to help you with O-ring material selection.

Nitrile butadiene rubber is one of the most commonly used rubber materials in oil seals and O-rings. It has good mechanical properties, resistance to mineral-based lubrication and grease, and has cost advantages, making it very widely used.


Advantages of nitrile Butadiene rubber (NBR) O-rings:

1. Low cost of use, nitrile rubber is the lowest cost of various rubber materials at present.
2. Nitrile rubber O-ring has good resistance to mineral oil and grease.
3. Nitrile rubber O-ring has good tear resistance and wear resistance.
4. Nitrile rubber O-ring has low temperature resistance, standard nitrile rubber /NBR can withstand low temperature -30℃, special NBR can withstand low temperature -40℃.
5. Nitrile rubber O-ring has good wear resistance.


The disadvantages of nitrile butadiene rubber (NBR) O-rings:

1. Nitrile rubber O-ring has poor high temperature resistance.
2. Nitrile rubber O-ring has poor ozone resistance.
3. Nitrile rubber O-ring has poor wind erosion resistance and aging resistance.
