Secondary procedureMüller Ahlhorn
APTIVTM Films can be used in a wide variety of secondary manufacturing processes, allowing designers and engineers the benefits and properties of APTIVTM Slide about the most diverse processes
to be able to use.
APTIVTM Foils can be applied to numerous materials using different adhesive systems. The adhesive system must be selected in consultation with the customer according to the environmental conditions of the end application. In most cases, pretreatment is the APTIVTM Foil surface required to ensure optimal wetting of the adhesive on the foil.
The different surface treatment options are listed below.
The APTIVTM The film extrusion line offers the option of turning the film surface on or off. Modified on both sides via a plasma treatment. This process significantly increases the surface energy and thus the adhesive strength to adhesives, inks, dyes and other materials. The selected plasma technology enables a high surface energy (over 55 dynes / cm) and also offers a longer storage time than with conventional corona treatments. Furthermore, the risk of a film puncture (pin hole) and an undesired rear side treatment, both side effects of the corona treatment, especially with very thin films, is eliminated. The internally measured surface energies have only decreased very slightly after a period of 12 months, so that a defined surface energy can be guaranteed over a period of 6 months (from the date of manufacture).
Other conventional surface treatment methods can of course also be used for the APTIVTM Foils are applied.
These include corona treatment, flame treatment, mechanical roughening or chemical etching.
APTIVTM Foils can be coated with numerous materials depending on the requirements. For coating, the APTIVTM Foils can be used in conventional equipment. For example, for adhesive tapes, adhesive systems are applied to the back of the APTIVTM Foils applied. These adhesive tapes are already available on the market with acrylic or silicone adhesives for a wide variety of applications. The combination of the unique properties of APTIVTM Foil with a special coating material enables customers to develop new applications that were previously not feasible. Other types of coating are B-stage heat-activated adhesive systems, UV curing systems, wear-resistant coatings or printable or laserable color systems.
APTIVTM Foil widths can be cut according to customer requirements.
APTIVTMFoils can be die-cut and thus offer customers numerous different shapes and sizes for thrust washers, seals, and other product components. Most processors use mechanical punching processes, but APTIV also uses laser and water jet cuttingTM Foils can be applied.
APTIVTM Foils are on the thermoplastic VICTREX® PEEKTM and can be hot-laminated with a number of other materials using press and roll processes. Often the APTIVTM Foils can be connected directly to other substrates without the use of an adhesive system. APTIVTM Foils have already been successfully hot-laminated with metal foils made of copper, steel, and aluminum without glue. The different possibilities for the production of multilayer substrates with APTIVTM Foil enable engineers to develop tailor-made solutions available directly from Victrex.
Welding and sealing
APTIVTM foils can be welded using different methods. The connection is achieved by heating the APTIVTM film almost to the melting point and at the same time exerting pressure on the weld seam. The welding process is carried out using heating element welding devices, ultrasound or
Laser welding equipment.
Due to the thermoplastic structure, the APTIVTM foils have a great advantage over thermosetting foils, as the APTIVTM foils can be reshaped in the deep-drawing process. Both amorphous and semi-crystalline foils can be used for deep drawing, taking into account the respective processing conditions. Foils or thin plates with a thickness between 6 μm and 1000 μm have already been successfully deep-drawn.
Laser marking, laser ablation and laser processing
APTIVTM Foils can be used for a high-contrast print on the foil surface
can be marked directly with lasers. About higher laser energies can also only
Partial layers are removed from the film surface. At even higher energies, the foils can be cut using a laser.
APTIVTM Films can be printed with common methods such as screen printing, transfer printing, and inkjet printing. It is recommended to subject the film surface to a plasma treatment before the printing process in order to ensure good wetting and thus adhesion of the printing medium to the film surface.
APTIVTM Foils can be metalized using a variety of methods such as vapor deposition, sputtering, electroplating, and direct lamination of the metal foils. Numerous metals that can be used on APTIVTM Foils are applied, especially aluminum, copper, tin, and more specific coatings such as ITO layers. Thicker metal layers can be applied to the APTIVTM Foils are applied.
