It has excellent heat resistance, water resistance, and electrical insulation properties!

The insulating sheet D581 and D581A are products that integrate laminated mica with silicone adhesive. They are characterized by very low emissions of smoke, odor, gas, and blistering at high temperatures. Due to their excellent processability, we are able to customize them into shapes requested by users, and they are widely used as various heat-resistant insulating components. Additionally, they have obtained UL94 V-0 certification, as well as UL Thermal Index 746B (D581: electrical properties 750°C, mechanical properties 450°C; D581A: electrical properties 760°C, mechanical properties 600°C). (UL File No. E58537) 【Features】 ■ Almost no smoke or odor from high-temperature heating ■ Minimal reduction in strength and insulation resistance after heating ■ Excellent water resistance, demonstrating extremely high electrical insulation in high humidity environments ■ Strong edge strength, providing excellent workability for winding operations such as heater wires ■ Easy to process with punching *For more details, please download the PDF or contact us.
