3mm - TEFLON, Tarflen, PTFE plate for gaskets circle ϕ 38.5cm

Teflon PTFE is a material belonging to the group of high-performance thermoplastics. It possesses the best thermal resistance among plastics with technical application: the highest temperatures of short-term use amount to approximately 300∘C; of long-term use - approximately 260∘C; the temperature range of use starts from −200∘C. Teflon possesses moreover very high chemical resistance. It is insoluble in all known solvents (below temp. 300∘C) as well as resistant to the action of atmospheric conditions. PTFE is characterized by, in comparison to other materials, the smallest coefficient of friction, as well as excellent insulation and the lowest dielectric coefficient. A characteristic feature of Teflon is its high density - 2.2 g/cm3.

PROPERTIES OF TEFLON (PTFE):

• very high temperature of continuous use - 200∘C

• large range of working temperature

• chemical resistance to diluted acids, fuels, solvents, hot water

• physiologically inert (odorless, tasteless, non-toxic)

• high thermal resistance (non-melting, self-extinguishing and very difficult to ignite according to UL94)

• good machinability

• excellent sliding properties

• good electrical insulation properties

• possibility of enrichment with stiffening additives

• high resistance to ultraviolet radiation

• unmodified and approved for food contact
