Tedlar® PVF: Top-Level Adaptability
Thin as a strand of hair, Tedlar® PVF is a film that is rarely used as one. Most of the time, it’s associated with other materials, protecting their surfaces. Do you want to leverage Tedlar® PVF’s exceptional qualities? There are at least four assembly methods for Tedlar® PVF.
Complexing + thermoforming
With a surface treatment, Tedlar® PVF film can be “adherable” and combined with a partially polymerized composite material.
The composite resin acts as an adhesive, and the adherence between Tedlar® PVF and the other material is obtained through two pressing stages and a heating procedure.
This complexing process can be associated with thermoforming:
We have placed the resin plaque on a thermoforming mold and the Tedlar® PVF layer above. Through hot pressing, we obtain a thermoformed piece covered with Tedlar® PVF. This technique works well for small, concave or convex radial shapes.
Examples of use: Meal trays made of polyester fiber, resistant to rubbing and cleaning.
Tedlar® PVF films can be made adhesive by applying a dry phase adhesive, which can be reactivated, then coating them with a covering that the user can peel off.
Example of application:
• Adhesive rolls of any dimension;
• Adhesive Tedlar® PVF layers;
Also called dry lamination, this procedure consists of bonding two soft films using a solvent-based adhesive, under great pressure.
Integration in an “in mold” molding procedure
Plastic films such as Tedlar® PVF can be directly integrated in procedures using molds or a matrix. The best example is plastic injection molding.
During the plastic injection procedure, before closing the mold, a Tedlar® PVF film is introduced. The piece is injected and the heat of the plastic matter induces bonding.
• Hospital equipment with Tedlar® PVF coating,
Laminating on metal sheets
In addition to being applicable on polymers and composites, Tedlar® PVF can also be used to protect metal sheets. Thanks to an adhesive specially developed by Dupont and a lamination procedure, Tedlar® PVF can protect and decorate:
• galvanized steel,
• stainless steel,
• aluminum sheets,
• aluminum/plastic panels
Examples of application
• Protective coatings, decorative architectural coverings.
• Easy-to-clean cladding panels.
• Protects corrugated iron roofs from mold growth.
Tedlar® PVF film can be used in several ways and integrated in several production chains.
