LINQTAPE HDT1S | Hydrogen detection tape


Main features
  • 1 and 2 inch Options
  • Visual H2 leak detection
  • Fast and reliable for H2 storage and transportation

Product Description

LINQTAPE HDT1S is an advanced solution for the visual detection of hydrogen gas leaks. This tape undergoes a rapid color change – transitioning from amber to black in as little as 10 seconds when exposed to hydrogen gas. The speed of this color transformation is contingent on factors like flow rate, temperature, time, and hydrogen percentage.

LINQTAPE HDT1S provides an effective means of detecting gas leaks, significantly improving response time by facilitating the identification of intermittent leaks. Its high sensitivity allows it to detect hydrogen leaks with concentrations as low as 1% H2, making it a reliable safety net in various applications. Once exposed to hydrogen gas, LINQTAPE HDT1S maintains its altered color permanently, ensuring a lasting indication of exposure. Applying this tape is a seamless process, akin to typical silicone/polyimide PSA (Pressure Sensitive Adhesive), making it user-friendly.

LINQTAPE HDT1S can be used in a variety of indoor or outdoor environments. It outperforms conventional portable or stationary sensors, offering superior detection and precise identification of hydrogen leak locations. This tape is less influenced by external factors such as wind, position, duration, or user skills. It provides comprehensive visibility, allowing for easy inspection of vertical and bottom faces.

Technical Specifications

General Properties
Adhesive Thickness
Adhesive Thickness
Adhesive thickness indicates the thickness of an adhesive layer.

It refers to the adhesive thickness of a single side so for double sided tapes it always needs to be multiplied.

Film Thickness
Film Thickness
Film thickness is the thickness of a backing film without taking into account any coatings or adhesive layers. It is measured in micron and the conversion factor to mil is 0.039.
25.4 µm
Total Thickness
Total Thickness
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.

Mechanical Properties
Adhesion Strength
Adhesion Strength
Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface, numerous physical, mechanical and chemical forces come into play, which may have an effect on each other.

Elongation
Elongation
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
67 %
Tensile Strength
Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.
Tensile Strength
Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.

What happens if these tapes are exposed to higher temperatures?

LINQTAPE HDT1S
is a Polyimide tape with a Silicone adhesive that is reactive to Hydrogen. When it comes to materials, this is very similar to our PIT1S so the operating temperature is 260°C. The problem lies with the reactive nature of the tape. The higher the temperature, the lower the time it takes to detect H2. Since some Hydrogen applications are in the negative °C, we know that it will take much, much longer for the tape to react at cryo temperatures.

On the upper limit, we have tested it for 6 months at 60°C and it works fine. We don't know how the tape would react in higher temperatures though. Technically, the materials should be OK but the high temp will probably affect the reactivity and cause all kinds of issues. The entire idea with H2 detection tapes is really to prevent things such as jet fire from happening by regular monitoring. In theory, we expect the tape to react since H2 will be present and the temperature caused by the jet fire will accelerate the reaction. In practice, we don't know.

it is important to note that the tape WILL react even with a very low % of H2 in the air (even 1% will suffice). It will just take much longer (hours) than if there were higher concentrations where you would expect a color change within a couple of minutes.
