Decomposition temperature

Plastics have a temperature limit beyond which their chemical structure is irreversibly damaged. This temperature is referred to as the decomposition temperature. If it is exceeded, the plastic begins to decompose, which significantly impairs its physical and chemical properties.

Adhering to the decomposition temperature is particularly important in thermal processing methods such as injection moulding, extrusion or welding. In these processes, local overheating can occur. If such overheating reaches or exceeds the decomposition temperature, the structure of the material is destroyed. This leads to an impairment of the material structure and significantly reduces the strength of the finished component.

It is therefore essential to monitor and control the temperature carefully during thermal processing in order to ensure the integrity and quality of the plastic components.
