Resin Barrier Checks Gas Permeation. (Applications in Plastics).
Use of DuPont's patented Laminar Technology and Selar RB (resin blend) barrier resins has attained a permeation level/rate of 0.08 to 0.21 grams per gallon per day, reports Scepter, commenting that this is well below the 0.40 grams per gallon per day rate regulated by ARB.
The one-step DuPont process, with controlled mixing and shear, enables the Selar RB to form dozens of overlapping, discontinuous, and elongated platelets. Depending upon the concentration of the Selar RB resin added to the blend, according to Scepter, the solvent barrier of laminar containers can be as much as 100 times that of containers made of an often-used competitive polymer.
Scepter notes the advantages of using DuPont Laminar Technology as follows. The barrier level of laminar containers can be adjusted to the exact level needed for each application, making the package more cost-effective. The barrier is permanent (i.e., cannot be scratched off or damaged in any way), and provides greater consistency. And the barrier resin can be either translucent or pigmented to any color. Moreover, says Scepter, compared with the use of fluorination -- an alternate means of reducing permeation in polymer gas cans -- Laminar Technology eliminates the danger posed by handling fluorine gas, which could leak into the environment or damage equipment.
Scepter reports that its ECO gas can and spout also demonstrates superior performance and durability, while being competitively priced. It promotes safety as well, the 1-, 2-, 5-, and 6-gallon containers featuring an automatic shut-off valve and automatic closure on the spout.
