Factory tint", done at the time of manufacture is generally not an applied film, but instead is done by dyeing the inside of the glass with a darkened pigment during glass manufacturing, an electrical process known as "deep dipping." The pigment gives the glass a tint, but doesn't provide UV ray protection or heat rejection like most window ...
Paint protection films use by the military has continued to the present day and 3M now makes a wide variety of aerospace and military films. [3] With time, however, the automobile industry began to take note of the protective benefits of PPF and it was soon being employed by race car drivers despite the difficulty of working with the original films.
The Continuous Liquid Interface Production method uses ultraviolet light to harden a photosensitive resin while the fabricated object is drawn up out of the resin bath. The continuous process begins with a pool of liquid photopolymer resin. Part of the pool bottom is transparent to ultraviolet light (the "window"). An ultraviolet light beam ...
Blow extrusion of plastic film. The manufacture of plastic film for products such as food packages, shopping bags, and continuous sheeting is achieved using a blown film line. [5] This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and ...
Another type of crystallization occurs upon extrusion used in making fibers and films. In this process, the polymer is forced through, e.g., a nozzle that creates tensile stress which partially aligns its molecules. Such alignment can be considered as crystallization, and it affects the material properties.
In manufacturing high-quality composite parts, such as in the aerospace industry, FEP film can be used to protect parts during the curing process. In such applications, the film is called "release film" and is intended to prevent the curing adhesive polymer (e.g. the epoxy in a carbon fibre/epoxy composite laminate) from bonding to the vacuum ...
Metalorganic vapour-phase epitaxy (MOVPE), also known as organometallic vapour-phase epitaxy (OMVPE) or metalorganic chemical vapour deposition (MOCVD), [1] is a chemical vapour deposition method used to produce single- or polycrystalline thin films. It is a process for growing crystalline layers to create complex semiconductor multilayer ...
Glasses (non-crystalline ceramics) also are used widely as host materials for lasers. Relative to crystalline lasers, they offer improved flexibility in size and shape and may be readily manufactured as large, homogeneous, isotropic solids with excellent optical properties.
