SEFAR® Architecture TENARA® Fabric is part of an environmentally responsible approach to architecture. The fabric is extremely durable and will not degrade during its long service life. It is free from odor and chemically inert. Uncontaminated scrap material and material used in architectural applications can be recycled.


SEFAR® Architecture TENARA® Fabric is 100% fluoropolymer with a backbone of high tenacity PTFE yarn. It has the following properties:

  • free of chlorine
  • no contribution to ozone depletion unlike chlorofluorocarbons (CFC's)
  • no contribution to the formation of chloro/bromo-dioxins or – furans ("dioxins")
  • free of plastisizers
  • free of stabilizers
  • free of catalysts

SEFAR® Architecture TENARA® Fabric is therefore harmless to the skin and completely odor-free.


The type of function and benefit a product provides – and for how long – is crucial for the ecological balance of that product. For example, if a product provides a function for twice the time of an alternative product, the negative impact on the environ­ment is significantly reduced. For the equivalent benefit to the user, production of the alternative consumes twice the amount of raw materials, energy resources, water and auxiliaries and generates twice the amount of emissions.

Due to their extremely strong carbon/fluorine bonds, fluoropolymers have unique properties: excellent chemical resistance, high resistance against extreme temperatures and UV radiation.

These properties make products produced from fluoropolymers extremely durable with long service lives, which, as explained above, has a direct positive influence on our environment.

Recycling and Disposal

The ability to recycle and reuse a material is beneficial to our environment and is normally preferred as compared to disposal by landfilling or incineration. Since SEFAR® Architecture TENARA® Fabric is 100% fluoropolymer and does not degrade during its useful life, it can be reprocessed and used in other applications.

PTFE is not classified as hazardous waste in Europe or the USA.

In a landfill, SEFAR® Architecture TENARA® Fabric is completely inert and will not degrade biologically. Consequently, it cannot contribute to hazardous lechates or gases.

In an incineration plant the materials contained within SEFAR® Architecture TENARA® Fabric are primarily converted to CO2 water and HF. The scrubbers in a state of the art munici­pal incineration plant that is capable of handling halogenated materials can capture the HF. The resulting HF emissions are far below levels that could harm people or the environment.
