AVKOSEAL-AL is a sealant, manufactured from 100% pure expanded PTFE.
It is typically produced as a tape and is less widely used in the form of a cord, plates etc.
The expanded PTFE comprises all the exceptional operation parameters of PTFE plus the additional features acquired in the process of expansion.
To facilitate the fitting AVKOSEAL-AL is provided with a one-sided adhesive backing strip with protective layer made from special paper, which is removed before fitting.
Due to its excellent flexibility and ductility AVKOSEAL follows very easily the shape of the sealed surface, and the adhesive strip enables the quickness of the fitting.
Apart from the flange sealing AVKOSEAL-AL may be successfully used in every other case of static sealing, provided that the working parameters fall into the range PTFE's values.

Advantages of the material |
- Chemical resistance to almost all aggressive mediums
(?? range 0 - 14);
- Temperature range: from - 240 °C to +290 °C,
short periods up to 310 °C;
- Physiologically safe - without taste and smell, nontoxic, does not contain soluble components, not influenced by microorganisms (moulds);
- Ensures cleanness of the medium;
- Hydrophobic, non ageing, resistant to UV - unlimited operational validity;
- In working conditions AVKOSEAL-AL does not change its hardness and brittleness;
- Nonflammable and noncombustible;
- Short fitting time, since AVKOSEAL-AL is ready for application and is not made from sheet material;
- Quick disassembly: AVKOSEAL-AL may be easily removed, without traces;
- No need of cutting (moulding) of the sealing;
- Complete use: no waste material;
- No need of additional mechanical treatment of the surfaces sealed: AVKOSEAL-AL is easily adapted and compensates deviations from shape and condition of the surface;
- The flexibility of AVKOSEAL-AL allows sealing of the most complicated configurations;
- Small storage costs - the material is packed in reels, as only several of them are sufficient for any sealing applications.
