Поли (метилметакрилат)

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.
