Depending on what you are planning to use the spacer for, I've found many plastic kitchen cutting boards seem to be very similar material. Very cheap at your local Ikea.
Delrin, UHMW and Nylon are similar, but different. Check in your local phone book for a Rubber and Gasket store. I worked with a r&g company for years and we sold it.

Duhh on me. I sell these things for commercial use. Found a cheap 1/2" bar cutting board for $2.80 in my cataloge, liquor not included. It's heat and chemical resistant, neither of which I need for the place it's going. Putting two together for the 1" thickness will work fine.
