PTFE

Polytetrafluoroethylene (PTFE), commonly known as Teflon, is a fluorinated polymer with incredible performance.

Its characteristics are unique: Teflon is not attacked by any chemically derived reagent. This is possible thanks to its slippery surface which does not allow any other material to adhere. Teflon, in fact, is completely hydrophobic. Additionally, it does not undergo degradation when exposed to light and its melting point is extremely high.

PTFE is characterized by a reduced coefficient regarding thermal transmission. Precisely for this reason it is considered a thermal insulator, it is not flammable and stands out for its stability even over long periods of time.


PTFE filled

Filled PTFE occurs when virgin PTFE is mixed with different fillers which can be: carbon, glass fibre, graphite, ceramic, nickel, stainless steel, bronze, MoS2, polyimide, etc.

Filled PTFE allows to improve some characteristics of PTFE, already the subject of particular interest from an industrial point of view, such as compressive strength, thermal conductivity or the reduction of the tendency to slide under load.

According to food regulations such as EC 1935/2004 (& EU10/2011), the material can be used in contact with food.
