Slit tapes TENSOGRAPH® are manufactured with the use of a whole range of TENSOGRAPH® graphite foil with further cut to any required width upwards 4 mm /  1/8 " with high precision which makes it an excellent filler for production of quality spiral wound gaskets and graphite die-molded rings.


Due to special patented technology TENSOGRAPH® tapes could be produced with high strength which solves the problem of breaking-up of filler for SWG's and graphite rings production.


Huge length of winding (up to 100m / 330’) makes possible longer continuous production and manufacturing of large diameter SWG’s.


APPLICATIONS:

Filler material for spiral wound gaskets and die-molded rings.





MAIN FEATURES AND PROPERTIES:

  • Huge length of winding (up to 100m / 330’);

  • Consistently accurate width and high strength;

  • Resistance to high temperatures;

  • Impermeability to gases and fluids;

  • Zero sulphur and halogen content;

  • Anti-sticking properties in accordance with ASTM F607;

  • Fire-safety approved (API Specification 6FB – Tensograph® C);

  • Absence of binders.
