Acrylic sheet having uniform distribution of coloring and mineral filler before and after thermoforming

Balance chain transfer agent, thixotropic agent and hibbsite content in the substrate, to a polymethyl methacrylate slurry the heating and deformation method for sticking process and wherein the formation of methyl methacrylate, wherein the movement of distribution of the coloring material and is hibbsite to unevenly is minimum, wherein a is - of catalyst to the impact strength of the product is deformation of the uniformity and improve the patterning the stability. A wherein the used in literature to compared, wherein one piece of the halogen is a dominant.
