Chemical impact on materials

 

The following table provides an overview of the chemical resistance of the main materials used to produce luminaries. Subsequent complaints can often be prevented by referring to  the information contained here.The nature and composition of the chemicals can cause material impairment of lights at different temperature ranges. Here are some examples where material impairment may occur:


- Food processing industries, kitchen, meat processing areas, dairies,  cheese manufacturing (detergents and other

   cleansing products used here)

- in areas where reinforced oils, greases and lubricants or chlorine fumes or direct contact with these materials is

   possible (please use diffuers made of PMMA in conjunction with and stainless steel latches).


The following table is based on an ambient temperature of approx. 22°C
