Q. What is the recommended filling amount when using mica as a filler? A. This is actually a surprisingly common question, but it cannot be answered definitively... Finding the right balance that maximizes the effect of the filler without compromising the function of the resin is quite challenging. The aspect ratio and average particle size vary for different sizes, which slightly changes the properties of the mica. For applications where you do not want any color to show, M grade (white mica) is recommended, while for those focused on physical properties, S grade (gold mica) is preferred. Depending on the type of resin and its application, the grade, size, and filling amount will all change, so I would appreciate the opportunity to discuss the optimal filling amount in a meeting. Lastly, if we consider only the properties of mica without taking into account the type of resin or the thickness of the film, the properties of mica tend to improve as the average particle size increases, and there is a tendency for the physical properties to significantly increase with a filling rate of 20% to 30% or more.
