Expanded PTFE tape



AVKOSEAL®


Expanded PTFE tape with adhesive stripe for flanges.
This 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® 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® may be successfully used in every other case of static sealing, provided that the working parameters fall into the range PTFE’s values.

AVKOSEAL® B


Expanded joint sealant, made from PTFE with filler glass and self adhesive strip. The tape has all unique characteristics of expanded PTFE – chemical resistance, temperature range –240 / 290°С, eliminating of “cold flow”, purity and gas impermeability, etc. Tape has better resistance on pressure, chemical resistance, especially to alkaline substances.


AVKOSEAL® R


Expanded joint sealant, made from PTFE with filler mica and self adhesive strip. The tape has all unique characteristics of expanded PTFE – chemical resistance, temperature range –240 / 290°С, eliminating of “cold flow”, purity and gas impermeability, etc. Tape has better resistance on pressure, low shrinkage and thermal expansion, stability of dimensions.
