BN1001 Boron Nitride Seal / Seal (BN Seal / Seal)

Catalogue Number	BN1001
Material	Hexagonal Boron Nitride
Purity	99%
Shape	Gasket/Seal

Boron nitride seals (BN seals) exhibit mechanical behaviour that corresponds with the technical properties of graphite. They provide a quantifiable level of electrical resistance that meets the defined criteria. Stanford Advanced Materials (SAM) has manufactured and supplied boron nitride seals over a sustained period.
