Successful Processing of TPE in a Wide Variety of Shapes and Formulations
Thermoplastic elastomers TPE are characterized by their elastic usage and thermoplastic processing properties. Based on the chemical-morphological structure, they are divided into TPE-S, TPE-O, TPE-E, TPE-A and TPE-V. Different methods are applied for the compounding of thermoplastic elastomers such as pelletizing or direct extrusion in film or sheet.
Numerous twin screw compounding systems from Coperion are in operation worldwide for the processing of thermoplastic elastomers in a wide variety of shapes and formulations. Coperion K-Tron feeders ensure that both elastomers and additives are added into the process consistently and accurately for an optimal result. Accurate feeding of mineral fillers is particularly important to avoid strain on the extruder due to overfeeding. A wide range of pneumatic systems and components are also available to handle the transfer of material to and from the extrusion process.
