Fire-resistant film: assess flame-retardant options

The term alone does not establish any particular product property. What matters is the requirement of your application and the test evidence for the specific material. A flame-retardant designation must be distinguished from heat resistance and thermal protection. The backing, adhesive layer and substrate may also behave differently. Check the evidence for the intended construction and actual exposure before selecting a film.

This cannot be guaranteed in general. Manufacturer evidence describes the tested product under specified conditions. In a converted shape, the material combination, geometry, backing and subsequent application may matter. Krückemeyer GmbH can cut or die-cut suitable films; whether the documented property still applies to the finished part must be clarified for each project. Send us the specific product evidence and your required version.

Flame retardancy concerns behaviour under flame exposure or the limited spread of flame. Heat resistance concerns exposure to temperature under stated conditions. One does not establish the other. For 3M Scotchlite Reflective Transfer Film 8735, the manufacturer describes flame-spread requirements under EN 469, dependent on the base fabric. Please specify the test requirement, temperature profile, duration and component construction separately for your application.

Useful details include the required function, the specific test standard or product evidence, the backing material and the substrate. Describe the heat exposure, duration and subsequent processing. For possible converting, we also need the required geometry and delivery format. This lets us assess whether an existing material and a cut or die-cut part suit the application. A material name alone is not enough.
