Reasons for Vacuum Metallization
Vacuum metalizing is the process by which the surface of a specific material is covered with a thin layer of a metallic substance.Aluminium is the most commonly used metal to serve this purpose. Aluminum is used because of various reasons such as, reflective properties, saving on cost and thermodynamic reasons. Vacuum Metallization uses the process of evaporation to enable the application of a metallic surface to a non-metallic material. A number of fields finds vacuum metalizing very intricate and useful for their day to day activities. Vacuum metallization has a number of functions. Examples are, for aesthetic purposes, insulation purposes and the increase of barrier properties. Below, the functions are explained in details so that you have a clue of what exactly vacuum metallization does. Read more great facts on emi coating, click here.

For Aesthetic Purposes
Vacuum metallization adds a unique appearance to surfaces. The PFT Technologies process gives a number of metallic finishes like reflective color finishes and many more finishes. The metalized objects usually have a highly reflective mirror like effect that is quite appealing to the eye. The use of dye and coating can also be used to offer a unique color to the substrate. You could try being creative by laminating vacuum metalized objects into other substrates like synthetic fabrics so that the material is unique and beautiful to the eye. With additional decorations, you will be able to achieve the aesthetic purpose. For more useful reference regarding SEOptiks, have a peek here.

For Insulation Applications
The thermal insulation systems used in the protection of spacecraft are all as a result of metallization by constructing layers of vacuum metalized polyimide films. The process also comes in handy for commercial and residential radiant barrier reflective insulation materials. The reason as to why vacuum metallization is ideal for insulation is due to the fact that is boasts of radiant properties and increased reflectance.

Vacuum Metallization Is Responsible For the Increase of Barrier Properties

An increased barrier property is another benefit that vacuum metallization has to offer. The metallization of a plastic object enables a great air barrier and moisture too. Food and beverage packaging without forgetting medical applications are some of the applications. Vacuum metalizing in addition minimizes the substrate light transmission enabling it to be an effective light barrier. The amount of vacuum deposited aluminum controls the light transmission. Examples of some of the functional barrier and insulation applications are; medical packaging, radiant barrier insulation, window care, aerospace thermal protection systems and electronic labels.
