PTFE Teflon sheets act as an insulator, limiting heat transfer from a heat press to your materials and protecting your designs from damage caused by excessive heat. They are reusable on both sides multiple times and can be easily cleaned of residues, ensuring a perfect final design. The PTFE Teflon sheet is made from high-quality materials that can withstand temperatures of up to 600 °C and is extra thick at 0.11 mm, allowing for repeated use. It can be used for non-stick baking sheets, ironing and clothing protection, heat transfers, ironing boards, and more.
