Slit tapes DEMIGRAPH® are manufactured with the use of a whole range of DEMIGRAPH® 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 DEMIGRAPH® 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
- Fire-safety
- Absence of binders.
