Functional SheetsFluorocarbon Fiber Sheet

Original sheet ideal for filtration and separation, electrical and electronic use, etc

Tomoegawa's fluorine fiber sheet "Tommy Filec" is a polytetrafluoroethylene (polytetrafluoroethylene = PTFE) 100% fiber developed by applying wet papermaking technology and heat treatment technology. It is a porous thin leaf sheet.

Feature 1Maintains the properties of fluororesin

Binderless porous thin sheet. 100% PTFE.

Excellent heat resistance and can be used continuously up to 260 ℃.^*
*Temperature range of fluorine resin

Excellent electrical characteristics (low dielectric constant and dielectric loss tangent, insulation)

Excellent properties such as flame resistance, non-adhesiveness, weather proof, non-toxicity and low friction coefficient.

Feature 2Utilizing TOMOEGAWA's papermaking technology

The texture is uniform. Realizes a thin sheet with a better texture than dry type sheets.

Contains no impurities. Contamination is less than 1PPM.

Sheet thickness of 50-1000μm and weight of 60-800g / m² are possible

Pore diameter (pressure loss) can be controlled (10 to 50 μm) by selecting fiber diameter and thickness.

Feature 3Customized on your request

Sheets with different fiber diameters can be laminated to create a graded pore size structure

Mixed with glass fiber, carbon fiber, etc.
