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:

 

Complexing-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.
 

Simple adhesion


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;
 

Laminating


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.

Example:
•    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.
 

Conclusion


Tedlar® PVF film can be used in several ways and integrated in several production chains.
