Hydrogen systems (from fuel stations to industrial piping) often use food grade inner linings — because these linings meet a set of properties: low permeability, low extractables/outgassing, chemical inertness, smooth surfaces, and regulatory traceability. The result: safer, cleaner, and more reliable hydrogen handling.     Why choose food-grade materials for hydrogen? 》Low contamination risk:Food-grade materials are formulated and tested to release minimal …

HOTOP produce high-quality high-performance silicone hoses lined with food-grade silicone for conveying cooling water, oxygen and hydrogen in fuel cell vehicle applications.             Conventional silicone hoses may contain trace amounts of extractable substances (volatile organic compounds), which will pose a risk to the fuel cell stack, so the inner surface of the hose needs to …
