Device for locating leaks in a vacuum-jacketed liquid-hydrogen transfer line consists of two Mylar discs, a source of nitrogen and helium gas, and a mass spectrometer. The outer jacket of the pipeline does not need to be removed for the locator to be used.
Physical and mechanical properties of aluminum- mylar-aluminum composite material for Echo II BALLOON
A thin-window proportional counter tube of 0.25-mil Mylar with a thin aluminum coating on one side permits efficient detection of long wavelength X rays. It is sufficiently rugged for long-term use in space or other demanding environments.
Commercially available aluminized Mylar, cork and fiber glass form a multilayered sealed system and provide rugged and economical field installed insulation for cryogenic /liquid nitrogen or oxygen/ pipe lines in an exposed environment.
Voyager thermal insulation requirements noting tests of vapor deposited Au on Mylar and Kapton
Liquid oxygen container rupture fire hazards - impingement effects of compressed oxygen gas and cryogenic supercritical oxygen against Mylar superinsulation in air
Electrical breakdown of Mylar micrometeoroid detectors on Pegasus panel under simulated space conditions
Thermal design of aluminized Mylar insulation system for cryogenic storage tanks - helium purging
Goldized Mylar or Kapton and other materials for planetary vehicle thermal insulation systems
Test methods and procedures to determine thermal conductivity of polyurethane foam and aluminized Mylar

Voyager thermal insulation requirements noting tests of vapor deposited Au on Mylar and Kapton
Lunar module multilayer radiation insulation for thermal control, testing aluminum coated Mylar and Kapton sheets
Multilayer insulation of prefabricated panels is developed for cryogenic storage tanks. System utilizes panels of aluminized Mylar separated by sheets of low conductivity polyurethane foam. Panels are self-evacuated by cryopumping of gaseous carbon dioxide at time of use.
Self opening em-operated secondary and ternary mylar diaphragms for expansion tubes and tunnels
Fabric knitted on conventional knitting machines uses commercially available yarns, has high aerodynamic drag capability, and is relatively inexpensive. The two yarn components used are 15-denier nylon monofilament and aluminized Mylar tape.
Self evacuating multilayer insulation system of aluminized Mylar and polyurethane foam for liquid hydrogen tanks
Multilayer composite consisting of alternate spunbond nylon layers and doubly aluminized mylar layers is used primarily in cryogenic thermal protection systems.
