Products made of combinations of rubber and thermoplastic offer several advantages over rubber-metal parts in function and costs; but in order to achieve these advantages the adhesion of the two components must be assured.

The common way to assure a good adhesion is the use of adequate adhesives. However  the use of adhesives has several drawbacks.

This presentation describes on the basis of product examples, that it is possible to achieve good adhesion between rubber and thermoplastic without the use of adhesives by using the so-called 2-components injection moulding technology.
