Materials Characteristics of NBR Rubber O-Rings
NBR rubber o-rings also called nitrile rubber o-rings or BUN-A o-rings.
The NBR rubber is synthesized from butadiene and acrylonitrile polymer. Acrylonitrile polymer content ratio is the following: 18-24%, 25-30%, 31-35%, 36-41%, 42-46%. Acrylonitrile polymer content ratio higher, the oil resistance of NBR rubber o-rings will better. NBR rubber o-rings have good abrasion performance, compression ratio and elongation. And X-NBR rubber o-rings have better abrasion performance than ordinary NBR rubber o-rings. NBR rubber o-rings operating temperature range: from -40¡æ to 120¡æ.
The disadvantage of NBR rubber o-rings: have not resistance to chemical corrosion.
NBR rubber o-rings are mainly used for the sealing action of the various oils container.
With the above characteristics, now NBR rubber o-rings are the most widely used and low-cost rubber seal products to use for the sealing action of the various oils container.
