A barrier fluoropolymer is used on the outer layer to suppress acid permeation in the hydrochloric acid line.
The "Junflon High Barrier PFA Tube" features an inner layer made of fluoropolymer PFA and an outer layer made of barrier fluoropolymer, making it an excellent barrier fluoropolymer tube. It is finished with a reliable two-layer structure through precision multilayer molding technology. The inner layer in the liquid-contact section uses semiconductor-grade PFA, providing high fundamental characteristics (purity, chemical resistance, non-stick properties, heat resistance) for semiconductor piping applications. The barrier fluoropolymer excels in resistance to acids (such as hydrochloric acid and nitric acid) and ammonia, effectively reducing acid permeation compared to conventional PFA tube piping, particularly in hydrochloric acid lines, which are prone to issues in semiconductor manufacturing processes, thereby minimizing adverse effects on surrounding equipment. Additionally, it can maintain fluid transparency over a long period. For more details, please download the catalog.
