Mylar polyester film

Curatorial Care of Works of Art on Paper. Intermuseum Conservation Association, Oberlin, Ohio, p.73). If the inks are not stable in water but are stable to methanol, the tapas will be treated with WEI T O Solution 3. If the inks are unstable in both water and methanol, the tapas will be encapsulated in Mylar polyester film and no further treatment will be attempted. 

Like amides, esters are common both in nature and in the chemical industry. Animal fats and vegetable oils are mixtures of esters, as are waxy materials such as beeswax and spermaceti. Plants often synthesize esters that give the characteristic tastes and odors to their fruits and flowers. In addition to making synthetic esters for flavors, odors, and lubricants, chemists have made synthetic polyesters such as Dacron polyester fiber used in clothing and Mylar polyester film used in magnetic recording tapes. 

Further important ccranercial flame retardants, developed by associates of Dr. Toy are Fyrol 99 (non-reactive for soft polyurethane foams) as well as halogen-free compounds like Fyrol 51 e.g. for polyurethanes or Fyrol HMP for the fire-protection of automotive air filters (29). In the application for polymer films, in addition to flame protection, Fyrol HMP was (new Victastab HMP) found to enhance the tensile strength of Mylar polyester films considerably. 

Polyethylene terq>hthalate is used in the manufacture of Dacron polyester fiber, Mylar polyester film, and Cronar photographic film base in the United States. In Canada, England, and some European countries, the commercial articles are called Terylene. In Germany, the film is called Hostaphan. Total capacity for producing polymer and its products in this country is in excess of SO anillion lb per year. 

In England and Canada and several European countries, polyethylene terephthalate fibers are sold under the name Terylene. In England the film is called Melinex, in Germany, Hostaphan. In the United States the products are trade-marked and marketed as Dacron polyester fiber. Mylar polyester film, or Cronar photographic film base.

The same polyester can be fabricated into a particularly strong film called Mylar. Mylar polyester film is used for the long-term protection of artwork and historical documents because of its transparency, strength, and inertness. Mylar is popular for its use in the manufacture of balloons for festive occasions. Mylar was also used to cover the 94-foot wingspan of the Gossamer Albatross, a human-powered aircraft used to fly the English Channel in 1979. Only two pounds of the polyester was needed to cover the entire wingspan, and the polyamide Kevlar was the material used for construction of the rudder of this aircraft In the United States, production of polyester fibers exceeds 3 billion pounds per year. 

Mylar polyester film is a product of the 50%/50% DuPont Teijin Films joint venture, dating from 1999, between DuPont and Teijin Limited. DuPont Teijin claims to be the world s leading supplier of PET and PEN polyester films and also supplies Melinex polyester film. Toray s joint venture in China is designed to produce PETP film for ultrathin capacitors. 

The DuPont Teijin Films joint venture, with Teijin of Japan, specialises in films and related products for electrical and electronic applications as well as for advanced magnetic media photographic systems and industrial packaging. Brands include Melinex and Mylar polyester films, Teijin Tetoron PET and Teonex and Kalodex PEN film together with Cronar polyester photographic base film.

First let us consider analysis in general. I am neither a spec-troscopist nor a physical chemist but an analytical chemist working in an industrial research laboratory primarily concerned with exploring and developing new polymeric films. By films I mean not photographic film but thin plastic materials such as polyethylene, Mylar polyester film, etc. In our laboratory an engineer or chemist may walk in with a sample at any time and ask us a number Du Pont trademark. 

It has been shown that some latent hardeners of the epoxy resins may corrode the aluminium wires or bonding pads. This corrosivity has been demonstrated for the complex of boron trifluoride and monoethylamine. In the specification NSA 77-25A, small dots of adhesive are applied to the aluminized side of a Mylar polyester film and allowed to stand in the room ambient without cure. After 48 h the dots are removed from the film by washing with acetone and the requirement is that there are no changes in the light transmission of the film. 

Inevitably, there was the desire to produce a film product, embodying the characteristics of the photo-fix paper. Coatings on MYLAR polyester film were produced. Here an anchoring sub-coat was required. 

Microfilm duplication Images on silver-based films could be duplicated either onto other silver films, or on diazo or vesicular media. The diazo films were relatively inexpensive but were believed to lack archival quality. Vesicular films on the other hand did not contain any dye-images, and thus were believed to be archivally stable. The microfilm industry at the time also promoted the use of microfiche, on which a micro-images were positioned on a 6" X A sheet of film. DuPont, as a supplier of MYLAR polyester film enjoyed significant sales of this for microfilm duplication products.
