BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation. [1] When metallized, it has [3] gas and moisture barrier ...
Aluminium is the most common metal used for deposition, but other metals such as nickel and chromium are also used. The metal is heated and evaporated under vacuum. This condenses on the cold polymer film, which is unwound near the metal vapour source. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres ...
This process gives useful (about 1 to 6 kgf/cm or 10 to 60 N/cm or 5 to 35 lbf/in) adhesion force, but is much weaker than actual metal-to-metal adhesion strength. Vacuum metallizing involves heating the coating metal to its boiling point in a vacuum chamber, then letting condensation deposit the metal on the substrate's surface.
E. I. DuPont de Nemours in Delaware, United States, first produced Dacron (PET fiber) in 1950 and used the trademark Mylar (boPET film) in June 1951 and received registration of it in 1952. [27] [28] It is still the best-known name used for polyester film. The current owner of the trademark is DuPont Teijin Films.
"Biaxially oriented PET film (BOPET) is manufactured with a film of the molten polymer being extruded onto a chill roll, which quenches it into the amorphous state. Biaxial orientation, then, occurs through a drawing process which can be either simultaneous or sequential. The most common way of producing BOPET is the sequential process.
Metalized is the debut album by the Canadian heavy metal band Sword, released in 1986 by the indie label Aquarius Records. Track listing
During the early 1960s, Brunswick Corp. conducted a research program to develop an economically viable process for forming metallic filaments. They started producing metallic filaments in a laboratory-scale pilot plant. By 1964 Brunswick was producing fine metal fibers as small as 1 μm from 304 type stainless steel.
out of 3 Mt bottles sold, 900kt of PET bottles (up from 600kt in 2008 [43]) were collected in 2018 (so around 1/3). 700kt of r-PET were produced for which the end uses were: 15% sheets & films; 35% bottles (1/5 for food contact). 40% fibres; 8% strapping; 1% other; In 2019, 81% of the PET bottles sold in Switzerland were recycled, [44] as in ...
