Price and sales of hydrogen leak tape factory from China
Features
• When the adhesive surface is exposed to H₂, the tape can change color from amber to black within 10 seconds (depending on flow, volume, temperature, time, and percentage of hydrogen);
• Extremely high sensitivity to hydrogen, capable of detecting hydrogen leaks with 1% H₂ concentration;
• Can slowly restore its original color in a hydrogen-free environment, reusable;
• Easy to operate, the method of use is the same as traditional silicone pressure-sensitive adhesives;
• Strong weather resistance, can be used in most indoor or outdoor environments.
Test Method:
1. Connect pipes of different diameters to intentionally create a state with hydrogen leakage
2. Inject 100% hydrogen gas at a flow rate of 100mL/min, visually inspect the state after about 1 minute
| High concentration hydrogen leakage was not detected at the tape winding position. | Hydrogen leakage was detected at the tape winding position, and maintenance personnel need to be reported immediately for repair or replacement. Test Results |
| Test Environment | Color Change When Removed | Color Change in Hydrogen Environment After Removal |
|---|---|---|
| High Temperature (70°C*6 months) | No discoloration | Became black |
| Low Temperature (-5°C*6 months) | No discoloration | Became black |
| High Temp High Humidity (85°C*85RH%*6 months) | No discoloration | Became black |
| Light Exposure (Sunlight exposure*6 months) | No discoloration | Became black |
| Water Immersion (Room temp water immersion*6 months) | No discoloration | Became black |
