ABSTRACT:
The invention relates to a process for bringing about a permanent connection between at least two components, one of which components is obtained by moulding of a thermoplastic elastomeric material, characterized in that the component is subjected to a treatment comprising the following steps:a. stretching of the component of thermoplastic elastomeric materialb. relaxation of the component subjected to step (a) at ambient temperaturec. placement of the component obtained sub (b) at the location of the desired connection in the objectd. exposure to an increased temperature of at most about 20° C. below the melting point of the thermoplastic elastomer.Application of the process of the invention, in particular during step (d), produces a shrunk connection which provides a permanent seal under tension.The invention may be applied for many types of connections and seals, for example body plugs, shrink-on sleeving, sealing rings, etc. Especially suitable, particularly in automotive applications, are copolyether esters.
