[High-quality material] Our microwave mica sheets are made of high-quality mica paper and silicone resin, providing excellent temperature resistance. The universal microwave mica panel helps maintain microwave oven efficiency, making it a practical accessory. [Reusable] This set includes 10 mica sheets that can withstand microwave use without deterioration, allowing for multiple uses. They are typically placed on the interior wall of the microwave oven cavity. [Extended service life] The microwave mica sheets help prevent water, oil, and other substances from splashing onto the magnetron or internal components. This helps maintain microwave efficiency and extends its lifespan. Without mica sheets, moisture and carbon buildup may damage the waveguide cover and affect magnetron performance. [Easy to Cut and Replace] These replacement mica sheets can be easily cut to fit your microwave using scissors or similar tools. Use the mica sheet as a template to mark and cut the new one for proper fit. [Wide Application] If your microwave mica sheet becomes damaged during use, such as when heating butter or chocolate, replacement is simple. These mica sheets are suitable for microwave ovens and can also be used in various household appliances like hair dryers, toasters, and stoves.
