Polycarbonate films with chemical resistance

The König Film Centre is active in the field of technical films for over 10 years and is a specialist in this product area. As part of our product range, we offer special films with particular properties.

These include films with a high resistance to chemical alkalis of the brand Bayfol ® (from the manufacturer Covestro ®).

A special mixture of polycarbonate with polyester makes Bayfol products obtain a surface that is particularly resistant to chemicals and cleaning agents. This makes thesde films the ideal solution for a wide range of industrial and graphic applications.

The König Film Centre offers you this film with different surface structures. While Bayfol CR 1-4 is polished on one side and fine matt on the other, Bayfol CR 6-2 has a matt surface on both sides. We offer Bayfol products in thicknesses from 175 µm to 375 µm in rolls. The roll length differs depending on the thickness. On request, we can cut rolls for you into rectangular sheets in the desired format.

We are pleased to advise you during the planning stage of your project and send you data sheets, safety data sheets and samples for the construction of prototypes. Tell us the format you require and we will immediately prepare an attractive offer for you. We cut and deliver all products in stock within a few working days.

Properties of chemical resistant polycarbonate films

Bayfol films from Covestro are a high-quality extrusion film made from polycarbonate (PC) and polyester. Bayfol® CR is characterized by an increased resistance to chemicals, dynamic strength and high flexibility. The films are particularly resistant to chemicals and can be cleaned even with aggressive cleaning agents. The colourless films are known for their excellent graphic quality and make them the solution for high-end applications.

In summary, they have the following properties:

  • increased chemical resistance.
  • good heat resistance.
  • high stability and flexibility (also over a wide temperature range).
  • electrical insulation capacity and good electrical properties.
  • cold and hot formable.

excellent printability with standard colours using screen printing and digital printing processes

Use and areas of application

The properties of Bayfol® CR polycarbonate film make it resistant to chemicals. It is the ideal material for the production of long-lasting and resistant membrane switches, nameplates, buttons and control panels.

Processing

This film made of PC and PBT has excellent cold and hot forming properties. The material is suitable for high-pressure forming (HPF) processes and has been established in film insert moulding (FIM) for many years. Bayfol® films can be printed in brilliant colours using screen printing and offset printing with commercially available inks that are suitable for polycarbonate.

No special accessories or tools are required to process the film.
