Damage analysis

The aging of plastics is an unavoidable process in which irreversible damage gradually takes place in the material. If suitable measures are not taken to delay aging or if the stresses are higher than expected, premature failure can result.

The effects of UV radiation, oxygen and moisture as well as heat and changing mechanical stresses damage the inner structure of the plastics. Material properties change. Plasticizers, which are intended to prevent the material from becoming brittle, or other additives are sometimes distributed unevenly in the material or escape from it. Color changes, violent fractures and fatigue fractures can follow.

We use suitable laboratory tests to analyze the cause of the aging processes: In this way it can be clarified whether the aging results from internal changes, for example from irregularities that have arisen during the manufacture of the materials. Inadequate mixing of the components can lead to differences in concentration and side reactions with disruptive reaction products.
UV light, moisture or aggressive media are the typical external influences.
With systematic damage analyzes based on our own laboratory tests and environmental simulation tests, our experts investigate damage to your plastic products caused by aging and embrittlement.
