Model: F4-1250 Filled
Teflon Sheet
Features: Thickness 3.0mm ~ 100mm
Materials: Graphite, Fiberglass, Carbon, Bronze
Main PTFE properties
Filled Teflon Sheet has a wide range of practicable temperature
from -180°C - +260°C and a wax-like surface to which anything
hardly Sheets. Filled Teflon Sheet has the lowest
coefficient of friction of all known solid materials. It has the best
electrical properties of all plastics.

In spite of PTFE's remarkable properties, the pure or unfilled PTFE is inadequate for many engineering applications. It is soft, and easy to deform under pressure. Now we can add some filler in PTFE to improve its:
- Mechanical properties
Fillers increase the hardness of PTFE and reduce cold flow or creep. Tensile strength and elongation usually are reduced depending on the filler type and percentage.
- Thermal properties
Filler increase thermal conductivity. Fillers also reduce liner coefficient of thermal expansion then increase thermal dimensional stability.
- Electrical properties
Some filler increase electrical conductivity.
- Tribological properties
Fillers reduce wear rate and friction.
