Polyester Mylar® Film

Dupont’s polyester research lead to a whole range of trademarked products, one example is Mylar® (1952), an extraordinarily strong polyester (PET) film that grew out of the development of Dacron in the early 1950s. Polyesters are made from chemical substances found mainly in petroluem and are manufactured in fibers, films, and plastics.

“Polyethylene terephthalate” (also called PET or PETE) was patented by British chemists in 1941, they saw that earlier research had not investigated the polyester formed from ethylene glycol and terephthalic acid. Polyethylene terephthalate is the basis of synthetic fibers such as polyester, dacron, and terylene.

Polyester Mylar® film has been used in a variety of applications that add value to products in virtually all segments of the world. After nearly 50 years, the future still holds great promise for Mylar®. Its excellent balance of properties and extraordinary range of performance capabilities make it ideal for a broad array of applications in the electrical, electronics, magnetic media, industrial specialty, imaging and graphics, and packaging markets and is available uncoated or coated in a broad variety of thickness and width.

Characteristics
• High tensile strength;
• Chemical; Dimensional stability, transparent;
• Gas and aroma barrier properties and electrical insulation;

Industry Applications
As a graphics template material and electrical insulating material for semi-conductor, laboratory environments. Also thermal insulation for houses and tents in cold environments, covering the inner walls with the metallized surface facing inward, thus reflecting heat back into the space. Insulation for houses and tents in hot environments, covering the outer walls with the metallized surface facing outward, thus reflecting heat away from the space. Metallized boPET film emergency blankets conserve a shock victim's body heat. Light insulation for indoor gardening and wildland fire shelters.
