Novaphit SSTC is made of high quality, expanded graphite and an expanded metal insert made from acid-proof-stainless steel AISI 304 - 1.4404, mesh (3 mm wide). 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 materials. The special geometry of the expanded metal produces a three-dimensional-mechanical bond with excellent stress relaxation and recovery of the graphite. Novaphit SSTC has an excellent workability, outstanding thermal and mechanical loading capabilities and exceptional chemical resistance.
