One of the characteristics of mica is its heat resistance! By using it as a filler, it is possible to enhance the physical properties against heat! It is also gaining attention as a non-combustible filler.
Heat Resistance Utilizing the heat-resistant properties to enhance the heat resistance of products. Additionally, it is advantageous that no physical property changes occur even under high temperatures during molding. Mica has different physical properties against heat between phlogopite and muscovite. However, both possess strong heat-resistant properties. 【Phlogopite】 - Melting Point: 1500°C - Dehydration Start Temperature: 800°C 【Muscovite】 - Melting Point: 1200°C - Dehydration Start Temperature: 350°C As shown above, phlogopite has even stronger heat-resistant properties. Furthermore, it is gaining attention as a non-combustible filler. Mica has a high aspect ratio and excellent barrier properties. By using it as a filler, the non-combustible effect is created, which can enhance the fire resistance of paints and resins. Additionally, there are specially processed micas that are made to be even more heat-resistant.
