HYDROGEN LEAK DETECTION TAPE

HYDROGEN LEAK DETECTION TAPE
Size: 25mm X 5meter X 0.3mm

 Hydrogen detection tape allows for the visual detection of hydrogen gas leaks by permanently changing color when
in contact with hydrogen gas. It acts as an early warning system for hydrogen leaks.
 This product is intended for use as a localized hydrogen gas indicator, and should be used as part of a
comprehensive gas detection system. It will not prevent H2 leaks. Customers should not rely solely on this product
to monitor the safety of a facility where flammable or hazardous gases are present.
 Surface should be clean, free of oil, moisture and dirt before applying. Pressure-sensitive adhesive tapes may
require pressure by roller, hand or press when applying. Not doing so may affect the general properties and
appearance. Please inspect your surface prior to application; this tape may not adhere well to extremely uneven
or distorted surfaces. Please remember to allow adequate time for full adhesive strength.
Hydrogen Detection Tape allows for the visual detection of hydrogen gas leaks by permanently changing color
when in contact with hydrogen gas.
 Hydrogen Detection Tape is a reliable and easy-to-use product that quickly detects the presence of hydrogen
gas. It changes color upon contact with hydrogen, making it a valuable tool for safety in industries like fuel cells
and petrochemical plants.
Features:
Easy inspection at hard-to-reach places
 Mitigate the risk of fire / explosion
 Less influenced by wind
Very quick detection
Doesn’t require tool and skills
 Close to leak points guaranteed contact before hydrogen dilution
 Can detect as little as 1% H 2 (99% N 2 ), 10ml / min. flow rate
 Provides visual detection of leakages
 See the leak: Tape quickly changes color, from amber to black (depending on the percentage of hydrogen).
 Safety: Provides an additional safety net for detecting gas leaks, and improves detection time by making it
easier to find intermittent leaks.
High Sensitivity: Can detect hydrogen leaks that contain as little as 1% H2 concentration.
 Irreversible Change: It will not return to its original color once exposed to hydrogen gas.
Environmentally Resistant: Can be used in most indoor or outdoor environments.
Hydrogen detection tape can be easily applied to, or wrapped around, pipes, flanges, fittings, valves, access panels,
etc. to immediately identify an exact hydrogen leak location.
The permanent color-change properties identify the exact leak location even if the H2 line is shut off.

Applications include and are not limited to power and chemical plants, transportation markets, Hydrogen co-
generators, fuel stations, storage tanks, compressors, new energy markets and more. Temperature vs. Reactivity

higher concentration will result in more immediate color-change. Immediate color change.
Easy-to-use
No electricity / battery required
Quick response time

 Strong adhesion
Non-toxic
Applicable to wide temperature change due to the combination of polyimide backing and silicone adhesive.
Recommended usage period up to 6 months, even outdoor.
 Irreversible color change
 2” width, 5 yards length.
Not influenced by wind, measuring position, during time, skills
High detection sensitivity due to its close proximity.

Temperature vs. Reactivity
• Tape was exposed to 100% H2 (6mL/min) at -40°C, -20°C, and room temperature to confirm color change
reaction.
• Result: Color-change to black was observed in 15min at -20°C, in 60min at -40°Cand in 5min at room temperature.
• Reactivity with H2, at higher temperature, higher flow rate, and/or higher concentration will result in more
immediate color-change
• Tape visually changes color, from amber to black, in as little as 10 seconds when exposed to H2 (depending on
the flow rate, temperature, time and percentage of hydrogen).
• Provides an additional safety net for detecting gas leaks and improves detection time by making it easier to find
intermittent leaks.
• Is highly sensitive and can detect hydrogen leaks that contain as little as 1% H2 concentration
• It will not return to its original color once exposed to hydrogen gas.
• Easy to use; applies the same as a typical silicone /polyimide PSA.
• Can be used in most indoor or outdoor environments.
• Superior capability in detecting the location of the H2 leak when compared to conventional portable or stationary
sensor.
Application
 Valves, flanges, fittings, connectors, couplings, parts under vibration, welded pipes, etc.
 Hydrogen Industry
 Hydrogen refueling station
 Hydrogen FCEV
 Hydrogen laboratory
