GRAPHITE LAMINATE
Our range of exfoliated graphite products are designed for demanding, higher
temperature applications typical of thepetrochemical and refining industries.
Manufactured from high purity exfoliated graphite, the product is available with a
variety of metallic inserts that increase its tensile strength, load bearing capacity and
improves handling characteristics.
Ultra high purity grades for the nuclear industry are also available.
Various proprietary brands such as KLINGER PSM-AS & SLS-AS,
NOVUS Fi & Ti, SIGRAFLEX HOCHDRUCK, FLEXITALLIC FLEXICARB RGS1, RGS2 & RGS4 are
available with:
Foil reinforcement, normally one or more 0.05mm thick 316 stainless steel or nickel
insertions laminated with the graphite sheet by means of a super thin chloride free
adhesive layer.
Tanged reinforcement, normally a tanged 0.10mm thick 316
stainless steel insertion mechanically bonded betweengraphite sheet, resulting in a
sturdy gasket material with excellent mechanical strength, capable of sealing
higherinternal pressures than standard foil reinforced grades.
Cut tanged gaskets can occasionally leave sharp edges; therefore adequate care must be
taken during handling, fitting and removal.
Both grades are available from SEP in sheet or cut gasket form with or without
‘Anti-Stick’ finish. Maximum sheet size1.5M x 1.5M, larger sized gaskets can,
depending on service conditions, be successfully dove-tail joined.
Cut gaskets are also available with a 316 stainless steel eyelet which removes potential
process contamination and improves the gaskets’ blow-out resistance.
