PTFE Teflon sheet acts as an insulator that limits the heat transferred from a heat press to your materials, protecting your designs from being damaged by too much heat. It is reusable multiple times on both sides and easy to wipe off any leftover residue, ensuring a perfect finished design. The PTFE Teflon sheet is made from high-quality materials that can withstand temperatures up to 600°C and is extra thick at 0.11 mm, allowing for repeated use. Can be used for non-stick oven liners, iron-on clothes protection, heat press transfers, ironing boards, and more.
