Apiezon® Greases

Measurements of sodium content for use in the electronics industry


Spectrographic analyses were conducted on Apiezon L and these results do indeed show that this particular Apiezon product is indeed "free" of sodium. Apiezon M grease is manufactured from the same raw materials and we would therefore expect the trace elements to be similar. These greases however are made by the molecular distillation of petrolatum, a natural product, and there is some variation, but only at the ppm levels. None of the analyses have ever picked up sodium, surprising, as it is usually present in trace quantities in most materials.
