Supranite PG XS
A restructured highly compressible modified PTFE gasket composed with only extra pure PTFE. The specific progressive structure of this quality allows high conformable faces, while ensuring maximum creep resistance. PMUC n°17-0345.
Supranite V01
Made of chemically and thermally exfoliated vermiculite, that gives high-temperature properties comparable to those of compressed asbestos gaskets. It is reinforced by a ultra-thin stainless steel core.
Supranite NGR AS
Made of nuclear grade expanded graphite foils and ultra thin stainless steels, laminated in a multi-layer structure capable of withstanding high stresses. The graphite and stainless steel are bonded without glue by an exclusive physico-chemical process that gives outstanding cohesion. PMUC n°17-0214.
Supranite PG AC
Composed of a homogenous bundle of PTFE fibers having an isotropic structure, resulting in high level of resistance to creep relaxation compared with conventional PTFE gaskets. PMUC n°17-0156.
Supranite PG AC F
High performing solution compatible with any chemical fluids, including concentrated fluorhydric acid and concentrated nitric acid. PMUC n°17-0217.
Supranite NGR
Made of high purity expanded graphite foils and ultra thin stainless steels laminated sheets in a multi-layer structure capable of withstanding high stresses.
Supranite PG VF
Made of chemically and thermally exfoliated vermiculite reinforced by synthetic fibres, in a matrix that gives higher mechanical properties than conventional elastomeric fibers gaskets at high temperature.
Supranite VS
Consists of a mixture of fibers associated with chemically and thermally exfoliated vermiculite. Compatible with most acids.
Supranite PGX 30 SRN
Comprises an homogeneous mixture of silicate fibres reinforced by synthetic fibres through an «X» – structured mesh that contributes multi-directional high mechanical strength. PMUC n°17-0125.
Supranite 2400
Compressed sheet material based on a blend of organic and inorganic fibers with a nitrile rubber binder system. Versatile and reliable solution.
