Hi, Anirut. It's not clear to me what you are looking for. A tank lining or heating coil that is resistant to chrome? Yes, teflon and several other fluoro type plastics are resistant. For tank linings, PVC is not fully resistant but is adequate. Or perhaps you're looking for a fluorinated fume suppressant?
