Поли (метилметакрилат) химические свойства, назначение, производство
Описание
Methyl methacrylate is one of the most common
methacrylates. This acrylic monomer, the essential
component of the fluid mixed to the powder, may
cause allergic contact dermatitis mainly in dental
technicians and dentists. Cases were also reported in
those using seulptured nails and in ceramics workers.
Химические свойства
white powder (or clear plastic sheet)
Использование
Poly(methyl methacrylate) is used in production of Carbonate-olefin based copolymer for molded plastics.
Определение
ChEBI: A macromolecule composed of repeating methyl methacrylate units.
Общее описание
Poly (methyl methacrylate) (PMMA) is an amorphous transparent thermoplastic polymer. PMMA is recognized as an optical polymer based on its refractive index of 1.49. Hence, it is used in optical fibers.It finds uses in biological applications because of its low water absorption capability and biocompatible.The maximum moisture content of PMMA is 1.71% and SBF absorption is 1.96%.Simulated Body fluid test (SBF) is a method to characterize the in vitro bioactivity of ceramic materials, by immersing the materials in an aqueous SBF solution.
Профиль безопасности
Questionable
carcinogen with experimental tumorigenic
data by implant route. When heated to
decomposition it emits acrid smoke and
irritating fumes. Used as the main
constituent of acrylic sheet, moldmg, and
extrusion powders.
