CHEMICAL RESISTANCE
This table provides an overview of the chemical resistance of the key materials used in luminaire construction. Subsequent problems and complaints can often be pre-empted by referring to this information. The type and composition of the chemical substances can cause the materials of the luminaires to deteriorate at different temperature ranges. Example applications where material deterioration may occur:
- Food processing industry, kitchens, meat processing areas, cheese factories, dairies (also due to the cleaning agents used here)
- In areas where oils, greases and lubricants or chlorine vapours occur more frequently or direct contact with these substances is possible – diffusers made of PMMA should be used in conjunction with V2A closures.
The information on chemical resistance refers to an ambient temperature of approx. 22°C.
