All plastics have some permeability to gases. ... For example, increasing the temperature only 63oF (20oC) will almost double the permeation rate through plastic parts. The Permeability of FEP Resins chart lists permeability data for various gases and vapors in terms of grams per 100 square inches of surface area per 24...

Temperature: Permeation rates increase with temperature. For any barrier, the permeation rate at the highest anticipated temperature should determine the design of the barrier system. Pressure: Higher pressures within the containment vessel will increase permeation rates through the polymer barrier.
