Silicone Rubber (Black)
MakerStock Silicone Rubber is available in white and black color and in thicknesses of 1/16in and 1/8in. Rubber more generally refers to polymeric elastomers -- stretchy materials. Natural rubber is made from the sap of rubber trees, but silicone rubber is a thermosetting polymer made from silicon, carbon, hydrogen, and oxygen. Silicone rubber is generally inert, stable, and temperature resistant. (This is the material used to make oven-safe rubber kitchen items.)
Silicone rubber may be laser cut. However, a residue may appear on the cut edge. The residue may be scrubbed off with soap and water.
