They're suited for heat-transfer projects such as basic T-shirts, tote bags, pillows, aprons, and are also described as ideal for pressing sewing projects.
Their layered construction directs heat to the design while managing moisture: the foil membrane reflects heat and blocks moisture vapor transfer, silicone foam provides insulation to shield the work surface from damaging heat, and the special inner liner wicks away moisture.
Each mat includes a durable outer cover for even heat distribution, a special inner liner that wicks moisture, a foil membrane that reflects heat, silicone foam for insulation, and a soft protective bottom barrier.
A durable cover promotes thermal conductivity and even heat distribution, the foil membrane reflects heat back to the project, and silicone foam provides insulation to maintain a consistent temperature.
They use a special inner liner that wicks moisture away to keep the pressing area dry, while the foil membrane prevents moisture vapor transfer; together the construction helps deliver clean, dry heat.
