3M™ Dyneon™ PTFE TF 1620 is a semi-free flowing powder grade polytetrafluoroethylene (PTFE) that’s ideal for anti-drip benefits and particularly useful in wire and cable and building material applications. These anti-drip characteristics can help retard flame propagation should the end-use part be exposed to extremely high temperatures. They are classified under UL94 V-0.

  • Meets ASTM D4894 Type IV, Grade 2 resin
  • Well-suited for billets and thin walled isostatic moldings
  • Provides good chemical stability and broad chemical resistance
  • Semi-free-flowing compression molding powder with high bulk density
  • Provides good electrical and mechanical properties
  • Able to mold at lower pressures compared with free-flowing grades

1-2-3, PTFE 
Polytetrafluoroethylene — commonly known as PTFE — is used as indispensable problem solver. It's commonly used in a broad variety of challenging applications from harsh industrial environments through architectural design elements to household applications. 3M™ Dyneon™ PTFE is selected for its technical excellence and reliability. 

3M™ Dyneon™ PTFE TF 1620 is ideal for molding of billets for skived films of greater than 200 µm, shaped parts, sheet stock and thinner walled articles. Dyneon PTFE TF 1620 is positioned between free flow and standard flow PTFE — and may allow the processor to use lower pressure than traditional free flowing powders. 

Fluorine Makes the Difference 
Quite simply, fluorine makes the difference. Fluoropolymers like Dyneon PTFE TF 1620 are outstanding materials, created by the presence and dominance of fluorine. Fluorine imparts special properties to fluoropolymers that make the difference for the polymer and the application. Like many of our PTFE products, the presence of fluorine gives Dyneon PTFE TF 1620 broad chemical resistance and an excellent operating temperature range from -328°F (-200°C) to 500°F (260°C). This PTFE meets ASTM D4894 Type IV, Grade 2. 

More than 50 years of Innovation 
For more than 50 years 3M Dyneon has been able to supply unique solutions to meet the increasing market challenges in developing and producing designated state-of-the-art 3M™ Dyneon™ PTFE products at the highest quality level. 

This goes hand-in-hand with our unparalleled commitment to research and customer support. Like all of our products, Dyneon PTFE TF 1620 is backed by skilled researchers at several 3M tech service laboratories. Collectively, our products benefit from hundreds of years of research and development, improving upon PTFE. Toward that end, we are in regular communication with customers who deliver feedback, allowing us to improve existing products and deliver custom solutions. All of this is part of an unrelenting drive to deliver top products to you.

Recommended Applications
  • Molding of billets for skived films of greater than 200 µm
  • Shaped parts
  • Thinner walled articles
