BARRIERS TO GASES
FROM MULTILAYER TO NANOFILTER MATERIALS
New nanocomposite products based on nano-clays are now
commercially available (e.g 6% in PA 6). The particular structure
of the filler allows the formation of barrier materials while
retaining most of the existing properties like toughness, clarity, oil
/ grease resistance, hot-fill heat...
