Is it possible to get a color choice?** A: black color is available for you **Q: Can this be used as a heat resistent backing behind a piece of SS stove backsplash to protect the wall?** A: It is heat resistant and works well with doir seals and such. If ya trying to protect a wall I would use cement board **Q: can this be used as a gasket for a wood pellet stove at the heat chambers** A: I would not use it there. The high end of the heat range for silicone rubber (there are various formulations with some holding up better at high temperatures than others) is about the same as an oven in your home (450° F). Without knowing or investigating, I would be willing to be the temperature for the stove application could be higher. I would use some of the fiberglass material made for wood/pellet stoves. **Q: What's the durometer?** A: This material has a 60+/-5 durometer hardness, Shore A Scale. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cuts easily. *by C***D on October 25, 2025* Served my purpose of altering the soles of my house shoes. ### ⭐⭐⭐⭐⭐ Good material.
