1、FAST AND EVEN HEATING: If you're building a for Mega Pro or for Mega S, you'll need a way to heat a 220x220mm or 220x240mm PEI or glass bed. This DC 12V 200W silicone heating pad is recommended for aluminum sheets. No need for SSR, heat quickly and evenly 2、APPLICABLE MODEL: 220x220mm building board heating pad built in 100K thermistor, wire length about 85cm. Suitable for Mega Pro, for Mega S, may be suitable for Artilery Genius, for Anet A8 A6, for Robo R2, for Wanhao Duplicator 6, for i3, for Voxelab Aquila, for Maker Select Plus, for Geetech, for Tev Tornad, for Tronxy X2, for Tronxy P802M, for Ultimaker 1 3D printers. It is best to confirm the size and shape of your hot bed 3、EASY INSTALLATION: Compared to other 3D printer components, installation is relatively simple. The adhesive is on the back of the silicone heating platform, just peel off the release film and attach directly to the aluminum plate platform, then properly connect the power cord to the silent motherboard and plug the thermistor connector into the socket for use 4、HEAT RESISTANT AND SAFE: Flexible silicone heater adopt imported silicone rubber glass fiber cloth, possess excellent performance, high temperature resistant of 200℃, long term working temperature up to 150℃. Ni alloy material resistant wire. Safe to use, high distribution density, uniform heating, long lasting without short circuit 5、PRODUCT ADVANTAGES: Silicone heater pad adopt imported materials, accurate machining technology, power is not false, better user experience, longer service life. High flexibility, flame retardant material, good thermal conductivity. The silicone wire adapts, heating evenly and quickly, and is safe to use
