PROPERTIES OF PTFE-GLASSTM FABRICS
Click here for specifications
The general properties of "FluonŽ" or "TeflonŽ" PTFE [Polytetrafluorethylene] are well known. The material resulting when PTFE is combined with glass fabric has the following general properties:-
- Superior heat and cold resistance
- Excellent chemical resistance
- High dielectric strength
- Dimensional stability under heat and pressure
- Low electrical loses
- Low friction, non-stick smooth surface
Electrical Grade "Hi-D"
Taconic "Hi-D" PTFE-GLASSTM electrical grade is a heavy coated super-smooth, high dielectric material. It has minimum outgassing, good abrasion resistance and high tensile and dimensional strength.
Premium Grade
Has an extra heavy coating of FluonŽ or TeflonŽ and are employed for special applications requiring a super-smooth surface such as laminate - release sheets and other specialised heat sealing and non-stick applications.
Standard Grade
Preferred for most applications, they have a smooth surface and exhibit remarkable anti-stick properties. Main uses are: release sheets in heat sealing and laminating processes; non stick surfaces for paints, adhesives, resins and food products.
Industrial Grade
Have a medium coating of FluonŽ or TeflonŽ and are used primarily in the packaging industry and as release sheets in the manufacture of plastic bags.
Porous Bleeder and Filter
Available over a wider range of porosity from 4mm open mesh to 50 microns. Principle uses are in filtration, strainers, pollution abatement applications, conveyor belts in fan drying and curing processes for many industries.
Crease and Tear Resistant
Taconic PTFE-GLASSTM fabrics can be given a special treatment making the finished product more flexible and resistant to crease and tear. Currently used in high speed packaging belts and flexing applications.
Semi-Conducting Tac-BlackTM
Provided with a carbon loading giving semi-conductive and anti static properties to the material. TAC-BLACTM PTFE-GLASSTM eliminates or reduces static problems in belt and slip sheet applications.
