Chemical characteristics:
P.T.F.E. possesses a high inertness towards all known chemicals, and is insoluble in all solvents up to temperatures as high as 250°C depend on filler type.
Mechanical properties:
Generally speaking, P.T.F.E. is a flexible material, endowed with fair tensile strength and high elongation at break.
The outstanding characteristics of P.T.F.E., among all polymeric materials, is represented by the wide temperature range (+200°C -200°C) over which its mechanical properties remain unaltered.
Electrical properties:
P.T.F.E. possesses exceptional and constant electrical properties during temperatures range from 100°C up to 300°C and at frequencies up to 10 cycles.
Resistance to ageing and weathering:
P.T.F.E. has high chemical stability, stands up well to aging effects, in long term aging tests, the sample exposed to different weathering conditions for years showed no weight loss.
Thermal properties:
P.T.F.E. is to be considered a thermal insulate having a low thermal transmission coefficient.
PHYSICAL and optical characteristics:
Parts fabricated with P.T.F.E. are opaque, white, black and bronze.
PROPERTIES OF FILLED P.T.F.E, to modify P.T.F.E characteristics is necessary to fill the powder with:
Glass fiber – carbon – graphite molybdenum –bronze metal oxides –ceramics- etc.
