Mylar – History and manufacturing
DuPont developed Mylar in the mid-1950s. In 1960 and 1964 NASA launched the Echo satellites, 100-foot diameter (30M) balloons of metallized 0.005 inch (0.13 mm) thick Mylar film.
In manufacture, a film of molten PET is cast on a roll and subsequently stretched orthogonally to the direction of travel. One side is normally microscopically smooth, while the other side contains microscopic asperities, which promote adhesion of coatings and printing media.
Mylar can be aluminized by sputtering a thin film of metal onto it. The result is much less permeable to gasses (important in food packaging) and reflects up to 99% of light, including much of the infrared spectrum. Like aluminum foil, aluminized Mylar has a shiny reflective side and a dull side. Mylar does not tear easily, unlike tin foil and aluminum foil.
Metallized nylon (or "foil") balloons used for floral arrangements and parties are often mistakenly called "Mylar". Many museums, archival institutions and those in the collecting areas of currency, stamps and comics use Mylar to protect their collectibles from damaging light rays.
In addition, farmers and hydroponics enthusiasts employ Mylar in their craft because the highly reflective nature of the film increases plant growth and yield by 35% or more.
Useful as an insulating material to reflect away heat and/or light, and as a light filtering element. Pkg. of 2.

It had been folded for packing; creases interfere very little; a roll would have been better but I did not find it listed as a roll. Thanks.JGJ - Thursday, May 27, 2010 The Difficulties of Handling Mylar Film Reviewed By: Bruce (West Bloomfield, Michigan) I single-handedly laminated the mylar film to a 4' x 8' sheet of 1/8" thick FRP (fiberglass reinforced polyester). The only way this was possible was to beg a scrap 12 foot-long 4"-diameter heavy carboard tube from Lowes's carpeting department to use as a mandrel to roll the film onto.
Then, using contact cement sprayed on both the rolled-up mylar and the FRP panel, I slowly unrolled the film in 6"-long increments (half the circumference of the mandrel) until all 32 square feet had been turned into a mirror (albeit it with web-like wrinkles).
Working with .001" thick film takes planning and patience. Being on Zoloft also helps keep one's temper in check. - Tuesday, April 22, 2008 Emergency Blanket Reviewed By: Solar (Pasadena, California) Light weight and easy to stash away in backpack. Just in case of emergency that you need to cover your body from losing temp so fast. May save your life, keep a pack and it is not taking too much space. Read More Reviews |
