Supranite Packing 602

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

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 850

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

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.
