Material Notes:
This property data is a summary of similar materials in the MatWeb database for the category “Acrylic, Impact Modified Sheet”. Each property range of values reported is minimum and maximum values of appropriate MatWeb entries. The comments report the average value, and number of data points used to calculate the average. The values are not necessarily typical of any specific grade, especially less common values and those that can be most affected by additives or processing methods.
