Features & Benefits

Product Overview
  • Chemical resistance parallels PTFE
  • Continuous use temperatures to 500°F (260°C)
  • Compared to PTFE
  • higher load carrying capability
  • 1/9 of the deformation under load
  • lower coefficient of thermal expansion

Fluorosint® enhanced PTFE’s unique properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to virgin PTFE. This bonding results in properties not normally attainable in reinforced PTFE. Fluorosint® grades offer an excellent combination of low frictional properties and dimensional stability.

Deformation Under Load

Fluorosint® PTFE HPV - Deformation Under Load

Engineering Notes

Due to its unique PTFE matrix, Fluorosint® physical strength characteristics are not as high as other advanced engineering plastics profiled here such as Ketron® PEEK or Duratron® PAI (formerly Torlon PAI). This compliance/ductility makes it ideal for seats and seals.

Coefficients of Linear Thermal Expansion

Fluorosint® PTFE HPV - Coefficients of Linear Thermal Expansion

  • Thermal Properties -  The figures given for these properties are for the most part derived from raw material supplier data and other publications.
  • (2) Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature (PBI, PAI & PI). DMA settings, oscillation amplitude of 0.20 mm; a frequency of 1 Hz; heating rate of 2°C/min
  • (3) Temperature resistance over a period of min. 20,000 hours. After this period of time, there is a decrease in tensile strength – measured at 23 °C – of about 50 % as compared with the original value. The temperature value given here is thus based on the thermal-oxidative degradation which takes place and causes a reduction in properties. Note, however, that the maximum allowable service temperature depends in many cases essentially on the duration and the magnitude of the mechanical stresses to which the material is subjected.
  • (4) Impact strength decreasing with decreasing temperature, the minimum allowable service temperature is practically mainly determined by the extent to which the material is subjected to impact. The value given here is based on unfavorable impact conditions and may consequently not be considered as being the absolute practical limit.
  • (5) These estimated ratings, derived from raw material supplier data and other publications, are not intended to reflect hazards presented by the material under actual fire conditions. There is no ‘UL File Number’ available for these stock shapes.
  • Mechanical Properties -  Most of the figures given for the mechanical properties are average values of tests run on dry test specimens machined out of rods 40-60 mm when available, else out of plate 10-20mm. All tests are done at room temperature (23° / 73°F)
  • (7) Test speed: either 5 mm/min or 50 mm/min [chosen acc. to ISO 10350-1 as a function of the ductile behavior of the material (tough or brittle)] using type 1B tensile bars
