The critical oxygen-barrier layer is sandwiched between two outer plastic protective layers, which not only withstand daily wear but also block moisture intrusion, This design prevents the oxygen-barrier layer in the middle from being scratched or affected by moisture, thus extending its service life.
High-performance barrier materials plays a role of "armor" for the pipe, with an oxygen permeability rate far below the national standard, effectively slowing down oxygen permeation. It prevents metal fittings from rusting and aging while extending the service life of the system.
With higher density and stronger surface hardness, it is more resistant to scratching and effectively withstands daily wear and tear.
It can maintain stable system operation even in environments where a regular working temperature rises up to 85℃.
