Chipquik makes pic related but sadly the datasheet says only the center pad is silicone, base is made from PVC.

However, the base look suspiciously similar to eBay "silicone" soldering mat which begs the question: are all those eBay "silicone" mats really made from PVC or has Chipquik gone full cheapskate here with PVC base when silicone would have been a better choice material-wise (heat resistance etc)?

>inb4 just get a wooden workbench
I would, but they come with a house that's financially unavailable for me at the moment.
