  • Three types of different smoothness: No.970-2UL general type, No.970-4UL heavy impregnated type, and No.9700UL surface-smooth type.
  • Polytetrafluoroethylene composite with stable molecular structure that is not affected by virtually all industrial chemicals or solvents.
  • Available for continuous use in a wide range of temperature; from -100°C to 260°C. Along with the superior dimensional stability of the cloth base material at both high and very low temperatures, it also has superior thermal properties compared to other thermoplastics.
  • Both dielectric constant and dielectric loss tangent are lowest and remain stable in a wide range of frencies.
  • Superior resistance to weather, moisture, and contamination.
  • Lowest static friction coefficient among all solid materials. It demonstrates unique self-lubricating property of lowering static friction coefficient as the load increases. With its non-adhesiveness and mold-releasing property, no adhesive substance attaches to it and makes mold-releasing easy when it comes into contact with adhesive substance.
