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.
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.
Compressed sheet material based on a blend of organic and inorganic fibers with a nitrile rubber binder system. Versatile and reliable solution.
Supranite Packing 557 EF
Developed for effective valve fugitive emission reduction. Constructed from exfoliated graphite tape reinforced with a specific Inconel ® mesh, treated with a graphited lubricant reducing frictions and a corrosion inhibitor.
Supranite Packing 545
Made entirely of thin graphite filaments having a High Specific Modulus and high mechanical properties, coated with a thin film of PTFE to facilitate fitting and running in. Increases packing-box life in most applications.
Supranite Packing 602
Made from high-density diagonal braiding of two complementary synthetic yarns : one with high mechanical strength, while the other provides excellent self-lubricating properties and facilitates the dissipation of heat generated by friction. PMUC n°17-0128.
Supranite Packing 530
Consists of very thin filaments of spectroscopically pure PTFE. Features outstanding chemical compatibility as it contains no other lubrification compound (oil,…) than pure PTFE dispersion.
Supranite Packing 601
Made from high-density diagonal braiding of synthetic and silicate yarns with high mechanical resistance. Associated with a chemically inert lubricant impregnated.
Supranite Packing 251 VR AS
The reference for PMUC braided packing used in nuclear power control valves. PMUC n°17-0019.
Supranite Packing 242 CP AS
For top and bottom rings for valve stem sealing set. Composed with an expanded graphite tape reinforced with Inconel ®. The reinforced yarns are then braided to produce this packing. PMUC n°17-0170.
Supranite Packing 557
Expanded graphite braided packing for valves, reinforced by Inconel ® wires in a specific structure that limits friction and improves the sealing performance.
Supranite Packing 660
New grade of braided packing made from an innovative organic yarn that combines high mechanical strength and limits shaft wear, associated with a dry lubrication system that increases packing-box life.
Supranite Packing 850
Produced by braiding pure calcium silicate yarn. The absence of an organic support in the production of these yarns results in a much smaller loss of volume at high temperatures than with most other products.
Supranite Packing V01
Made from chemically and thermically exfoliated vermiculite ribbons reinforced with Inconel ® mesh. This construction allows excellent handling characteristic, minimize extrusion under compressive load and improves blow out resistance.
Supranite Packing 801
Made of long pure amorphous silica filaments that do not loose weight and volume at high temperatures. Made of yarns braided in the mass, giving the product excellent mechanical resistance and ensuring a good seal.
Supranite Packing 650
Made with Supranite Packing 850 tape vulcanized for mechanical resistance and contains in its core the Supranite Packing 600. Customised manufacturing on request.
Supranite NGN 02 AS
PMUC graphite tape reference. More than 20 years of positive feedbacks and returns of experience obtained from plants. PMUC n°17-0077.
Supranite Packing Sets
Packing sets with Supranite NGN 02 AS or Supranite NGN 03 AS rings placed into two anti-extrusion rings in Supranite Packings 242 CP AS or 243 BF AS. Metal insert can be included inside the rings in order to facilitate future extraction. PMUC qualified.
High Performance Expanded Graphite Gasket. Designed to work under metal / metal contact. PMUC n°17-0200.
