Endurance, bond strength, resistance to chemicals, heat and the environment – the requirements for structural bonds are more demanding than ever before. In addition, there is a strong trend towards "less is more," especially in the consumer goods sector. Devices are becoming increasingly smaller and consequently so are their bonding surfaces. This is where standard adhesive tapes reach their limits. However, tesa HAF®'s area of expertise begins precisely where nothing else works. Alongside enormous adhesive strength, it also trends toward "less is more" because it has no initial bond strength (also known as tack). Instead, it is activated by heat: At temperatures above 120°C, the bond is irreversible.
The film is ideal for forming customized die-cuts – even the very smallest. For example, in many smartphones, tesa HAF® sits under the camera lens on the back of the mobile device as a component that is only 0.4 mm wide. Anyone who gets into a car can also rely on this mini-sized adhesive with gigantic strength because its immense endurance and heat resistance make it suitable for use on friction linings in gearboxes or rotor magnets in electric motors, among others.
