Backing and adhesive mass of high temp adhesive tapes

When faced with a bonding problem in a high temperature application, the question always arises: which high temp tape should I choose ? What are the different possible backing materials? Which reference should I use?

This page will help you understand the advantages of each material and its resistance in a hot environment.

First of all, what does "high temperature" means? Generally, it referes to a product that resists temperatures from 150 °C.

Adhesive masses are of great importance for the choice of the adhesive tape and for the heat resistance:

Thermosetting rubber: up to 130°C
Acrylic: from -40°C to 150°C
Silicone: from -60°C to 316°C

The possible backing materials are: polyester, glass cloth, Teflon PTFE, Kapton polyimide, aluminium, masking paper, canvas.

Another possible alternative is the choice of a 100 % acrylic adhesive foam with closed cells from the 3M (VHB tape), ADEZIF or TESA: some references have the particularity to resist efficiently to heat.

What are the temperature classes for insulating media?

For most heat resistant adhesive tapes, their heat resistance is defined by the continous temperature and the peak temperature they are able to withstand.

For thermally insulating materials such as glass cloth and Kapton, which are used in the electrical and electronic industry, 5 temperature classes have been standardized for the continuous operation of electrical equipment.

The thermal stability of insulating materials and insulation systems is then guaranteed up to the maximum temperature indicated by class. Their dielectric characteristics are then maintained.

Here is a summary table of the different thermal classes for insulating materials:

CLASS TYPE	THERMAL STABILITY OF THE INSULATION GUARANTEED UNTIL:
	Continuous temperature	Peak temperature
Y	80°C	105°C
A	105°C	130°C
B	130°C	155°C
F	155°C	175°C
H	180°C	255°C

Common high temperature applications

Protection of parts subjected to high temperatures, such as in car engines or exhaust pipesheat resistant
Holding or shrinking of coils
Reflection of heat
