Franklin's Lamitex® Cryogenic neck tube materials maintain their impermeability to liquid nitrogen & liquid natural gas (LNG) in extreme handling conditions. Lamitex® glass/epoxy neck tubes have high strength characteristics and have tested better in 'drop tests' than our leading competitor's tubes. Lamitex® Cryogenic pipe insulation has been used in critical insulating applications, including the supercollider laboratories and in the transportation of liquid natural gas. Franklin has machined glass epoxy neck tubes, small diameter straw tubes, profiles and parts from glass epoxy sheet materials for a wide variety of cryogenic applications.
