Nylon 6 additives
Nylon 6 additives
(OP)
Hey guys,
I have an electrical component made from Nylon 6 and i'm trying to determine what additives were utalized. An FTIR scan showed nothing out of the ordinary for Nylon 6. Thinking metal oxides may have been used, i did an x-ray analysis and my results were...
48% Al2O3
30% MgO
14% SiO2
8% Na2O
I don't deal with polymers to often, so i'm trying to figure out if these are typical additives for Nylon 6 under elevated temps.
From what i have read, phosphines are typically used for elevated temps and sometimes mica powder is used. I'd just like a second opinion on these results or if there is a better way of detecting these.
Thanks guys,
-Mikey

We have the WINEDS software hooked up to a Tracer North detector on our SEM. I don't know how exactly the software does it, but ours will generate your normal EDS spectra. You can then identify your peaks through thier respective energy levels. To do a quantitative analysis it gives you the option of searching for either elemental values, or metal oxides.
To answer your question though... or rather not answer it, i don't exactly know how it can tell what is bonded to what. Sorry

Copper sulfate may be used where a cleaner base colour is thought to be desirable.
If high dielectric strength is required, proprietary antioxidants are used.
Glass fibre is very commonly used to improve flex mod and heat deflection temperature, but it can cause warpage in moulding. If warpage is a problem, mica or wollastonite can be used, but they are not nearly as effective as reinforcements due to the lower aspect ratio.
