Thermoplastic elastomers (TPEs) have the elastic behaviour of rubber and the processability of thermoplastics. The chemistry, houses and processing of those fabrics are mentioned during this evaluation. professional grades are being brought for particular functions and with exact homes, comparable to softness or processability. The overview is followed via round four hundred abstracts from the Rapra Polymer Library database.

Specific machine parameters will vary by TPE type and are driven by the rheological behaviour and the sharpness of the melt temperature range. Table 3 summarises some typical injection moulding conditions for several types of TPE. The process temperatures are typically adjusted to the melt temperature range and kept low enough to allow a short cooling time. Cycle time is kept as short as possible by keeping the mould temperature and melt temperature as cool as possible. When temperatures become too low the surface appearance and mechanical properties of the moulded component will be compromised.
