TPE refers to elastomer alloys composed of varying amounts of thermoplastics and elastomers.

Thermoplastic elastomers containing a cross-linked rubber component are designated as TPE-V. The cross-linking and dispersion of the EPDM, along with the addition of larger amounts of softener, place significant demands on the compounding technology.

Decorative film, used for vehicle interiors, for example, can be produced using Coperion extrusion lines in a single-step process. The intermediate pelletizing stage—typical for plastics and other products—is eliminated in this in-line compounding system. This significantly lowers both the investment and operational costs, as well as reducing the energy demands of the production process.
