Is this stuff OK for pull-through method?

[KiwiMoose]

I saw a you tube video of that funny German woman and she used a plastic matting which the lye virtually dissolved as she was trying to pull it though.
This stuff is sold as PVC non-slip matting for drawers etc, and is dishwasher/washing machine safe. I thought it would be good to cut shapes into and use as a pull-through for a slab mold.
Can anyone advise?

I think you are talking about Marie Nadeau’s video. The mat she used was some kind of plastic that the lye destroyed. The PVC material may be okay to use, but I would test it. If you are planning to make soap not using the mat, put a little batter on it and let it sit for awhile. If it stays intact you should be good to go. I’d let it sit for 15-20 minutes, or however long you think you will need for pouring, plus a litt extra time for good measure.

I use PVC non-slip mats for covering my soap airing racks and have not seen any ill effects so far (I'm 99% sure I saw PVC as an acceptable material for working with soap which was why I chose it), but @dibbles provides sound advice as always Can't wait to see what you create next!

If it’s PVC it is highly resistant to lye (sodium hydroxide), according to this website:

You will need to scroll through the alphabet to get there...

PVC is resistant to alkalis (lye), but it's not ideal for situations where the PVC gets much above room temp -- it can soften, deform and stretch with heat. I think it would be fine for your purpose, but Dibbles has a good suggestion to test it.

Since you are Down Under from me I am not sure if it is the same as we have here.

Our Liners for Drawers is kind of like a Foam mat. You can pinch it and is squishes.
If that is the same I would say Don't.
If it is Flat and Hard plastic give it s shot
