Protect Heat-Sensitive Fabrics: The foam cover pad is designed to protect garments and enhance heat press application during heat printing, especially on heat-sensitive materials like nylon. It helps prevent scorching, protects buttons, zippers, and snaps, and can be used to create a strong bond between the heat transfer material and the fabric. Three Thicknesses to Meet Different Needs: These heat pads are helpful when applying dimensional emblems and patches with a heat press. We recommend using a thicker pad for thicker emblems. The 4 inch x 8 inch pad is available in three thicknesses: 1/8 inch, 1/4 inch, and 3/8 inch. The 4 inch x 8 inch size is ideal for small applications. Even Pressure: The heat pad helps distribute pressure evenly across the design area, ensuring a consistent bond between the heat transfer material and the garment, even when pressing around seams, zippers, or buttons. Two Ways to Use: One way to use a silicone foam pad is to place it over the design area to protect the garment from direct heat, and another way is to place it under a T-shirt to provide support and more even pressure. Using both methods together can offer extra protection for garments and improve heat transfer results. Wide Application: It can be used with various heat transfer materials and on different garment types, including those with buttons, zippers, and other embellishments, making it suitable for customizing T-shirts, blankets, pillows, hats, mugs, and more.
