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

Tomoegawa's fluorine fiber sheet "Tommy Filec F" is a polytetrafluoroethylene (polytetrafluoroethylene = PTFE) 100% fiber developed by applying wet papermaking technology and heat treatment technology, which is only manufactured by our company in the world. 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 ℃.
• 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.
