Technical adhesive tapes by application

When insulating, it is not only the nominal value of the dielectric strength that is decisive, but also its long-term stability under temperature stress, media contact and stress over time. Differences are particularly evident in the tracking behaviour, resistance to ageing, the layer structure and reliable processing for demanding geometries.

Typical differentiating features

• CTI / tracking behaviour vs. pure kV values
• Thermal class vs. real continuous load
• Layer structure for complex geometries
• Behaviour under moisture, impregnates and media

During bundling, the permanent mechanical load, abrasion and the relaxation behaviour of the adhesive act together on the joint. It is crucial that the bundle reliably retains its shape and position over the entire period of use - regardless of temperature, vibration or type of assembly.

Typical differentiating features

• Fabric vs. film vs. hybrid carrier
• Long-term creep behaviour
• Noise and abrasion behaviour
• Manual vs. automated processing

When bonding, pure adhesive strength is only one of several factors. The decisive factor is the balanced interaction of adhesion, cohesion and shear strength. These parameters must be precisely matched to the respective substrates, the available installation space and the specific process requirements.

Typical differentiation features

• PSA vs. transfer vs. structural systems
• Dynamic vs. static loads
• Substrate pairings (metal / plastic / coating)
• Rework and disassembly capability

When masking, the focus is on a temporary protective function. Constant adhesion properties, resistance to media and clean, residue-free removal are crucial - even after exposure to temperature or chemicals.

Typical differentiating features

• Residue behaviour after exposure to temperature and time
• Resistance to chemicals, paints and media
• Edge stability
• Automation capability

Sealing means ensuring a permanent sealing effect under compression. The resilience, minimised setting behaviour, media and temperature resistance as well as reliable implementation in series production are decisive factors here.

Typical differentiating features

• Foam vs. film vs. hybrid
• Setting behaviour over time
• Temperature and media resistance
• Process reliability for serial printing

Damping is a specifically designed material function for reducing vibrations and noise. The relevant frequency range, the specific damping behaviour of the material, the temperature dependency and a permanently stable mechanical connection to the assembly are decisive.

Typical differentiation features

• Degree of damping vs. stiffness
• Temperature dependence
• Ageing under load
• Combined fixing and damping function

Thermally conductive adhesive tapes enable targeted heat transfer from the heat source to the heat sink. At the same time, they fulfil fixing and tolerance compensation functions. Their thermal conductivity depends on the direction and is designed for specific functions. The heat flow in the z-direction, the quality of the contact surfaces, the ageing behaviour and reliable electrical insulation of neighbouring components are of decisive importance.

Typical differentiation features

• Thermal conductivity vs. thermal impedance
• Gap-filling capability
• Long-term stability under temperature
• Electrical insulation effect of the environment

Electrically conductive adhesive tapes fulfil defined functions, including the transmission of electrical currents, targeted earthing and the shielding of electromagnetic interference. A low and stable contact resistance, direction-dependent conductivity, ageing behaviour and the controlled dissipation or shielding of electrical currents are of decisive importance.

Typical differentiating features

• Surface vs. volume conductivity
• Directional dependence
• Contact stability over service life
• Combination of conductivity and insulation functions
