PFTE Gasket Manufacturing 

Not all PTFE (Polytetrafluoroethylene) is made alike. Teflon™, created by DuPont and now owned by the Chemours Company continues to be the highest standard in the industry. Used in everything from frying pans to dental floss, the toughness, high purity and non-stick nature of the Teflon™ brand is known for its excellent performance properties in almost all environmental conditions. Teflon finds broad application in the food, beverage, dairy, pharmaceutical and biopharmaceutical industries, showing excellent resistance to heat, steam, strong acid and bases, and vegetable oils. Teflon™ is compliant with FDA and USP VI criteria as well as a host of other worldwide regulations and standards.

Newman Sanitary Gasket provides Teflon (PTFE), TFM, Silverback Gasket Manufacturing for the food, beverage, and pharmaceutical processing industries. We only use virgin Teflon in the manufacture of our Teflon parts. We work to continually improve the performance of our Teflon products through our license agreement with Chemours to ensure our customers receive the highest quality products and service they deserve.

  • Manufactured from pure virgin Teflon® from DuPont.
  • FDA and USP Class VI compliant.
  • 3-A Certified

TFM™ Modified PTFE

TFMTM is a trademark of DyneonTM, a 3MTM company.  Almost identical in chemical composition to Teflon, TFMTM is made by adding a very small amount of a different fluorine structure to the polymer chain. This results in is an equally pure, equally chemically resistant, fluoropolymer with better properties.

  • TFMTM will not shed layers like PTFE.
  • TFMTM has less porosity than PTFE (so vapors don’t pass through as easily)
  • TFMTM holds its shape under compression better
  • TFMTM has better flexibility and flex-life
  • TFMTM compliance meets that of Teflon (FDA, USP and more)

Not all modified PTFE is made the same, and different grades give different properties and performance.  Newman has done the work to choose genuine DyneonTM TFMTM and the best grades from Dyneon for the application. Whether it is gaskets, Newman NewFloTM diaphragms, or composite parts, Newman compounds perform and last.

Silverback™ (50/50 blend of TFM™ and 316 Stainless Steel)

Take the performance of TFMTM and add low carbon, passivated, high purity Stainless Steel for stiffness, and Newman Silverback™ material is the result.

  • Silverback™ gaskets outperform other materials in continuous steam exposure
  • Silverback™ gaskets have the chemical resistance of PTFE
  • Silverback™ gaskets are FDA and USP Compliant
  • Silverback™ gaskets can be used from extreme cold to extreme heat: -110°F (-78 °C) to 400°F (204 °C)
  • Silverback™ gaskets can outlast most other materials in continuous and multi-use processes.

Although best used in fairly constant temperature processes, Newman Silverback™ can also be used with thermal swings, provided that appropriate hardware and gasket conditioning is considered. Contact Newman for technical support.
