I want to use it to cover a hole in a plastic wall.** A: Hi, The PTFE sheet isn't very flexible, but it isn't rigid. I don't think that it would be a suitable material for your job, mainly because of its non-stick properties. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Teflon sheets *by P***L on 16 December 2023* Ideal for making liners for my airguns ### ⭐ Not really heat resistant *by I***A on 24 November 2024* The plastic sheets deformed after heat was applied ### ⭐⭐ Thought i had ordered 3mm thickness *by K***S on 4 November 2023* Not thick enough fir my application .
