TPE refers to elastomer alloys which consist of different quantities of thermoplastics and elastomers.

Thermoplastic elastomers with a cross-linking rubber component are specified as TPE-V. The cross-linking and dispersing of the EPDM as well as the addition of larger quantities of softener make high demands to the compounding technology.

Decorative film, which is used for vehicle interiors for instance, can be produced with Coperion extrusion lines in a single step process. The intermediate pelletizing typical for plastics and other products is omitted in this in-line compounding. This considerably reduces the investment and running costs as well as the energy requirement of the production process.
