Choose heat-resistant self-adhesive film

Start with the actual temperature profile at the component and the duration of exposure. Then check the film backing, adhesive and intended function against the information for each product. A rating for the backing alone does not establish how the self-adhesive film will adhere in service. Information about the surface, further stresses and your processing method also helps with selection. Assess a specific format against the material and the intended application.

No. Heat resistance describes a documented ability to withstand exposure during processing or use. Heat activation means that heat is needed to activate an adhesive bond. By contrast, the manufacturer's data sheet for 3M ET 92 specifies a pressure-sensitive silicone adhesive that needs no heat for application. The appropriate principle depends on the substrates, bonding process and required result. Compare the details of the product you intend to use.

No. Temperature resistance, flame behaviour and thermal conductivity are separate properties. A product-specific statement on flame retardancy is available for 3M ET 92; it does not establish that the whole range is fire-resistant. Equally, a temperature rating for a film backing does not establish the thermal conductivity of a bonded assembly. If your component needs either function, specify it clearly and check the documentation for a suitable product.

Tell us the required application result, the surface, temperature profile and any additional stresses. For converting, the width, length or contour, your processing steps and the required delivery format also matter. Krückemeyer GmbH can convert suitable base material into application-specific dimensions and shapes. Whether a cut roll or die-cut part retains the intended function must be checked against the particular material and geometry.
