minimum application temperature

The minimum application temperature is a decisive factor for the performance of plastics. At low temperatures, the molecular chains of the material become less mobile. This restriction of mobility causes the plastic to lose elasticity and toughness, which makes it brittle.

It is important to note that below its minimum application temperature, the material is not suitable for applications that are exposed to impact loads. In such cases, the brittleness of the material can cause it to break or fail.

However, it should be pointed out that the minimum application temperature is less relevant if the application of the material does not involve impact loads. In such situations, the material can still fulfil its function despite low temperatures, as long as no sudden loads occur.
