Summary
- Store most plastic and rubber materials at low temperatures (a freezer is acceptable for most polymers) and maintain relative humidity levels below 50%.
- Maintain low oxygen environments and low light levels (30 lux with a maximum UV exposure of 1500 µW/m2, but preferably no light) to enhance stability of plastics.
- Monitor the condition of plastics carefully to prevent damage to nearby artefacts.
- Support flexible objects in their desired shapes.
