PB11000 SERIES

Modified PTFE

Modified PolyTetraFluoroEthylene (mPTFE) is a chemically modified form of PTFE. Less than 1% of the fluorine atoms in the PTFE chain are substituted by a perfluoroalkoxy. Modified PTFE has a lower molecular weight than PTFE, which means that particles fuse better.

As a result, the end product is more compact, with fewer voids, and with better weldability than PTFE. The perfluoroalkoxy modifier in modified PTFE acts as an inhibitor of crystallization, ensures better distribution of the crystallites in the amorphous matrix and therefore, the cold flow is drastically reduced. 

Depending on the percentage of modifiers, PB11000 materials can be used in applications that require high creep resistance or high flexibility.

PBY Material Codes:

PB11000D - Modified PTFE Creep Resistance

PB11001D - Modified PTFE High Flex

Modified PTFE Properties:


  • Smoother Less Porous surfaces lead to less contamination
  • Improved permeation resistance
  • Longer flex life than PTFE
  • Improved creep resistance and increased stiffness
  • Higher dielectric strength yields superior high-voltage insulation
  • Weldable / Fusible
  • Infinite Shelf Life

Typical Applications


  • Corrosion-resistant lining of steel parts
  • Valves and pipes
  • Gaskets requiring low deformation under load
  • Improved Weldability lends well to semiconductor applications
  • Carriers for silicon wafers and flat panel displays

Requirements


PB11000D meets ASTM D4894 Type III Grade 1 requirements.
