Gasket→Graphite Gasket
Engineered Graphite with Steel Mesh Gasket ZW#6600
ZW#6600consists of high-quality, expanded graphite (purity level at least 99%) and an expanded metal insert made from acid-proof stainless steel AISI 316L – DIN 1.4404 foil (0.15mm). Under high pressure the expanded graphite particles are compressed to films without adding any binders or fillers. The expanded metal is then incorporated into the sealing material. The special geometry of the expanded metal produces a three-dimensional-mechanical bond with excellent stress relaxation and recovery of the graphite. Novaphit SSTC XP has an excellent workability, long-term non-stick properties, outstanding thermal and mechanical loading capabilities and exceptional chemical resistance. The exceptional product properties open a wide spectrum of applications including the most extreme operating conditions, novaphit products are especially suited for dynamic and static sealing assemblies where durability and resistance to deformation, flexibility, loading capacity and a good chemical resistance are mandatory.
