What are flame retardant films?

Many applications require flame retardant films that meet certain fire protection classes or specifications. As a film supplier, the König Film Centre offers you flame retardant and thus fire resistant films in various thicknesses and surfaces.

These are flame retardant films with consistent insulation properties and good printability. The main advantages of these products are

  • Flame retardancy according to UL94 V0.
  • Excellent thermal and electrical insulation properties.
  • High temperature resistance.
  • High mechanical strength.
  • Excellent dielectric strength.
  • Low moisture absorption.


Due to their versatile material properties, flame retardant films are extremely popular and important in many industrial sectors. As a wholesaler, we can supply you with the film of your choice in sheets or rolls. We stock flame retardant films made of  the raw materials polycarbonate, polybutylene terephthalate and polyertherimide.

What do I need a flame retardant film for?

Flame retardant films can be used for various applications and uses:

  • Thermal insulation.
  • Insulators and spacers.
  • Labels and overlays.
  • Printed circuit boards.
  • EMI shielding.
  • Other fire protection items.

In these applications, the finished part must pass a specific fire protection test. For this reason, developers look for materials that are also flame retardant and meet certain standards.

Which fire protection standards are relevant?

When is a special film flame retardant? There are different approvals and fire protection classes that vary from country to country. Since many parts made of film are used worldwide, the American standard UL 94 has become the standard in the industry. This is accepted worldwide and is more important than most country-specific standards such as B1 in Germany or M1 in France.

Fire protection standard UL 94

UL 94 is an established standard of the American test laboratory Underwriters Laboratories. According to this flame retardant standard, the burning properties and fire safety of plastics are tested.

Fire resistance according to UL 94 V0

Class V0 is the highest flammability class of plastics according to UL 94.

In the test according to UL 94 V (Vertical Burning), a vertical piece of plastic burns. The fire behaviour of the respective plastic results in the classification into classes V0, V1 or V2. The UL 94 V0 specification is the classification with the best fire resistance.

Our product range of flame retardant films

As a specialist in technical films, we offer various products that meet the UL 94 V0 fire protection standard. These include flame-retardant film solutions made from the raw materials polycarbonate, polybutylene terephthalate and polyertherimide from various manufacturers.

Fire-resistant polycarbonate films

Polycarbonate film is characterised by outstanding optical transparency, high mechanical strength and high temperature resistance. These properties also apply to polycarbonate films with flame retardancy.

In our range we offer flame retardant polycarbonate films in different material thicknesses which we distinguish as follows according to colour and surface:

  • Crystal clear (highly transparent), glossy PC flame retardant film.
  • Matt, colourless PC flame retardant film.
  • Black PC flame retardant film.

Flame retardant PC-PBT film

A blend of polycarbonate with polybutylene terephthalate (PBT) makes these film solutions resistant to elevated temperatures. They also feature excellent electrical properties combined with exceptional processability and surface quality.

Flame-retardant PEI film

The central property of the plastic PEI (polyetherimide) is its temperature resistance. The manufacturer of PEI film products specifies a processing temperature of up to 200 degrees Celsius. This sets the PEI film apart from most technical film solutions.
