Grilamid L16 nat vs. Grilamid L 25 nat
Grilamid L16 nat vs. Grilamid L 25 nat
(OP)
I have a small Polysulfone, 20% Glass, 15% TFE part with OD of .03".
This part will be overmolded with injection molding material. This material has 93% NeFeB powder, and the rest is Nylon 12 binder. The resultant part OD is .1".
We have used Grilamid L16 nat as the binder so far.
The compounder wants us to switch to Grilamid L25 nat for some reason.
Comparing the data sheets I found Grilamid L25 nat to be HIGH viscosity Nylon12, while Grilamid L16 nat is LOW viscosity Nylon12. Data sheet for Grilamid L25 nat provides information for EXTRUSION only, not for MOULDING.
Would Grilamid L25 nat be a good substitude for Grilamid L16 nat in my case?

He has suggested that the compounder may find it easier to work with L25 (more back pressure for him to enable better/easier pelletizing), but you will be unlikely to injection mould it. L16 is the "go to" grade for magnetic material compounding.
