PMMA ist ein Werkstoff mit hoher Festigkeit, Steifigkeit, Wärmeformbestandigkeit und Kratzfestigkeit. Er zeigt eine hohe optische Transparenz und Glanz bei guter Witterungsbeständigkeit und ist gegen schwache Sauren und Alkalien, nichtpolare Losemittel, Fette, Ole und Wasser beständig. Jedoch ist die Anfälligkeit gegenüber ...

The PMMA Revolution By Kirk Goodrum introduCtion Almost 175 years ago, the low-slope rooing membrane industry began with the use of a ield-applied liquid component and a reinforcing fabric. Built-up roofs using coal tar or bitumen were the standard …
In this article, we review the application of conventional free radical polymerization, atom transfer radical polymerization (ATRP) and coordination polymerization for preparing high molecular weight PMMA. The …
PMMA ist ein vielseitiger Kunststoff mit einer Reihe von einzigartigen Eigenschaften. Das Material ist stark, hart, klar und transparent sowie UV-abwehrend und UV-beständig. PMMA ist feuchtigkeitsresistent und …
PMMA jest sztywnym, transparentnym tworzywem termoplastycznym o doskonałych właściwościach optycznych.. Naturalnie bezbarwny, o wyjątkowej przezroczystości, może być barwiony w celu uzyskania szerokiej gamy kolorystycznej. Przepuszczalność światła widzialnego wynosi 90-92%, a przepuszczalność promieni nadfioletowych ok. 70%.
Nesse caso, o PMMA é utilizado em microesferas, numa forma semelhante ao gel. No Brasil, o PMMA para preenchimento subcutâneo precisa ser registrado na Anvisa, pois é um produto de uso em saúde da classe IV (máximo risco). De acordo com o órgão, há registros de produtos para essa finalidade há mais de 10 anos no Brasil.
