Topaz 251, High-tech PU PFTE Duo Topaz Bimicro Topaz Carbon Membrane

Topaz 251: High-tech PU


Topaz bimicro®

Topaz Carbon Membrane



Thanks to its chemical composition, this special membrane system on the basis of high-temperature-resistant polyurethane meets the most demanding of use and processing requirements while offering the following characteristics:
  • softening point of approx. 230°C (scorch test)
  • hydrophilic properties
  • good stretching properties
  • non-blocking properties
  • washfast and sterilisable
  • highly suited for seam sealing and patch application
Topaz 251 high-tech PU membranes are used in all workwear/PPE applications.

Trans-Textil is placing a further new development on the market in the form of the Topaz bimicro® membrane. This unprecedented product combines the characteristics of a microporous ePTFE membrane with those of an equally microporous protective polymer layer for high water vapour transmission and variable air porosity at high water impermeability. Topaz bimicro® can be optionally upgraded with Cocona® natural technology™ utilizing activated carbon derived from coconut husks.

Further membrane systems
  • High-tech compact hydrophilic PU system
  • Microporous PU systems for high breathability and impermeability
  • Microporous hydrophobic ePTFE systems for maximum breathability and a certain degree of water resistance
  • Compact hydrophilic PES systems for an excellent price/performance ratio
