What are self-healing cutting mats made from?
When I was in graduate school, I took a seminar class from a chemist whose work in developing self-healing polymers was widely admired. I had seen these self-healing cutting mats in the MicroMark catalog, and always wondered what they were made of. So I asked him, in class. He looked at me like I’d grown a second head: “You mean to tell me you’ve seen self-healing polymers on the market? In a consumer product?” Later I brought him the catalog, and showed him the listing. He was stumped, and more than a bit dubious.
