A step up from standard NBR, for applications that outgrow it but don't need full FKM performance.
An upgraded NBR offering better heat and chemical resistance without stepping all the way up to FKM.
Higher mechanical strength, oil resistance, and heat tolerance than standard NBR.
Applications where standard NBR falls short but full FKM performance isn't necessary.
Oilfield drill seals, automotive timing belts, air conditioning seals.
A middle-ground choice between NBR's cost and FKM's premium performance.
