Expanded mineral graphite possesses very special characteristics.
In fact, it is very resistant to almost all chemical agents, can withstand both very low and very high temperatures and high pressures, has good thermal and electrical conductivity, resists ageing well, has good constant springback and is flexible.
It is also easily workable. It is often reinforced to increase its strength and durability with grated or smooth steel sheets.
The main ones are:
Graphite Without Armour
Seals made of flexible expanded graphite without inserts. They have a high resistance to creep and a very good seal even with uneven surfaces or low clamping loads.
Graphite Armata Piana
Graphite gaskets with a stainless steel foil insert give a longer service life combined with a drastic reduction in liquid and gaseous fugitive emissions, ensuring greater safety.
Perforated Graphite
It performs up to 10 times better than rubbers such as NBR rubber. Exceptional resistance to high temperatures.
Multilamellar graphite
Reinforced graphite gaskets with multiple stainless steel foil inserts provide greater pressure resistance and sealing security.
Graphite Without Armour
Seals made of flexible expanded graphite without inserts. They have a high resistance to creep and a very good seal even with uneven surfaces or low clamping loads.
They are also used in the presence of cycles or thermo-mechanical shocks with high pressures and temperatures. They are used in pipes with aggressive vapours or fluids with the exception of strongly oxidising agents.
Graphite Armata Piana
Graphite gaskets with a stainless steel foil insert that gives a longer service life combined with a drastic reduction in liquid and gaseous fugitive emissions, ensuring greater safety.
They have excellent creep resistance and good sealing at low clamping loads and with surface irregularities. They are also used in the presence of cycles or thermo-mechanical shocks with high pressures and temperatures. They are used in pipes with aggressive vapours or fluids with the exception of strongly oxidising agents.
Perforated Graphite
Graphite gaskets with a perforated stainless steel foil insert provide greater pressure resistance and sealing security.
They have excellent creep resistance, chemical stability and good sealing at low clamping loads and with surface irregularities. They are also used in the presence of cycles or thermo-mechanical shocks with high pressures and temperatures. They are used in pipes with aggressive vapours or fluids with the exception of strongly oxidising agents.

PTFE Certificato
Viene realizzato aggiungendo al PTFE delle polveri additivanti come fibre di vetro, carbone, grafite, bisolfuro di molibdeno, bronzo e polveri di ceramica. Queste componenti aggiuntive variano le caratteristiche del PTFE e possono, a seconda delle diverse concentrazioni, aumentarne la durezza, la resistente alla compressione, la resistenza all'usura, ridurne il coefficiente di dilatazione termica e variarne la resistività di volume e la resistenza superficiale.
MB Guarnizioni lavora differenti tipologie di PTFE caricato, le principali sono:
PTFE VERGINE + 15% FIBRA DI VETRO
PTFE VERGINE + 25% FIBRA DI VETRO
PTFE VERGINE + 15% GRAFITE
PTFE VERGINE + 25% CARBONE SOFT
PTFE VERGINE + 25% CARBOGRAFITE
PTFE VERGINE + 60% BRONZO + 2% CARBONE
PTFE Espanso
Questo polimero possiede un'elevata resistenza chimica e un'alta stabilità chimica nei confronti dell’eccitazione termica, infatti le sue caratteristiche permangono idonee fino a temperature di 260°C. Inoltre ha ottime proprietà anti-adesive, basso coefficiente di abrasione, elevata stabilità dimensionale ed estrema resistenza all’invecchiamento con facilità nel conservare l'elasticità nel tempo.
