Trelleborg UltraFlex Liner

All in one...

The Trelleborg UltraFlex Liner with silicone coating represents a new generation in liners. An all-encompassing solution for some of the most common challenges you face when rehabilitating pipes: bends and transitions.

90° bend

Got bends?

Negotiating multiple bends up to 90° 

  • Minimal creasing / optimum bend mobility
  • No calibration hose required even in down-pipes
  • Low pressure requirement during installation and curing

Got transitions? 

Allows up to 2 changes in diameter
  • Universally applicable for vertical and horizontal pipelines
  • Longitudinal expansion can be calculated 
  • Achieves minimum 3 mm [1/8"] wall thickness even in over-expanded areas

The fast and ambient curing Trelleborg Epoxy FC30

The ideal solution for plumbers and small companies who do not want to invest in expensive equipment.  

With a short pot life and curing time, Trelleborg Epoxy FC30 is quick and easy to install. It impresses with its compatibility with wet surfaces, good mechanical properties, and high chemical resistance. It is - like all Epoxy resin systems developed by Trelleborg - solvent-free and free of volatile organic compounds (VOC's)

The innovative Trelleborg UltraFlex Liner

Its unique silicone coating makes the difference!

The perfect interplay between leading-edge textile production and the special formulation of the silicone coating has resulted in a high-tech product, which fulfills the highest demands when it comes to quality and versatility and is setting new benchmarks.

The Trelleborg UltraFlex Liner is extremely flexible and temperature resistant, making it suitable for hot water and steam curing methods. 

A jetting resistant test, conducted on the Trelleborg UltraFlex Liner in 2015 checked the effects of high-pressure water jetting on rehabilitated drains and sewers, The results: The Trelleborg UltraFlex Linersuccessfully passed the high-pressure water-resistant test up to a maximum pressure of 120 bar. 

Liner End Cap

The practical LinerEndCap Technology

More efficiency for open-end liner installations!

Using the specific LinerEndCap method will make your job easier and quicker: in just one step and without the need of an additional calibration hose  the wetted liner can be inverted and installed. With the LinerEndCap applicated previously to the liner end with a special adhesive the Liner will be closed for the period of installation. So the user can set up the liner with the required pressure until the resin has cured.

High mechanical properties for a sustainable solution

Specially developed for the steam curing method the Trelleborg Epoxy HC120/120 Plus is able to withstand high temperatures without distortion and is resistant to chemicals ranging in pH value from 2 to 13. 

Trelleborg Epoxy HC120/120 Plus ensures a rapid and homogeneous impregnation. It is very easy to use due to its ample pot time of 120 minutes and a short cure time of just 45 minutes, once the curing temperature of 80 °C/176 °F, measured between the liner and host pipe wall, is reached. 

After steam curing, it provides high mechanical properties that ensure the fulfillment of the statical requirements.
