It is the temperature region where not only the modulus but almost all the physical and mechanical properties change rapidly during heating or cooling. It is the temperature at which the plastics material changes to become almost rubber-like.

Channels for cabling, guard rails. High fibre content. 1 Injection moulding This method is the most familiar and widespread of the techniques used with unreinforced thermoplastics. It has spawned a number of related procedures which are increasingly used to produce reinforced plastics products. In the most basic method, resin is mixed with short glass fibres and converted by means of an extruder into small cylindrical granules. The granules are heated and when molten, forced under pressure by means of an Archimedean screw into a split cavity mould, where cooling takes place.
