Acrylic sheet having uniform distribution of coloring and mineral filler before and after thermoforming |
摘要 |
Ranges of chain-transfer agents, thixotropic agents, and alumina trihydrate content are balanced to minimize migration or maldistribution of coloring matter and alumina trihydrate during curing of methyl methacrylate in a syrup including polymethylmethacrylate and also during subsequent heating and deformation in thermoforming, to achieve constancy of impact resistance and improve stability of patterns even in deformed portions of formed sheets.
