What is the role of rubber adhesive?

In the mixing of rubber materials with other additives added directly to the rubber material and in the vulcanisation temperature to achieve the two materials combined with each other, itself does not directly produce physical adsorption between materials or chemical bonding cooperation, but can promote the adhesion of the chemical substances produced. Therefore, they are also called additive direct bonding agents.
In the processing of rubber products such as tyres, conveyor belts, hoses, etc., one or more reactive chemical substances are added, which can chemically bond rubber to fibre fabrics or steel wire skeleton materials at vulcanisation temperatures.
It is used in the adhesion of rubber fibre, rubber-metal, rubber-plastic, etc. to produce chemical bonding at the interface, and belongs to functional additives.
