PMMA PLEXIGLAS V920

Plexiglas? V920 is a General-purpose thermoplastic acrylic resin formulated for injection molding and extrusion applications. It is characterized by its very high melt flow. Plexiglas? V920 has excellent weatherability and optical properties allowing it to excel in applications requiring outdoor stability, high quality surface appearance and/or precision optics. Plexiglas? V920 is easy to process due to its exceptional thermal stability, extrusion melt strength, and excellent tool surface reproduction and release properties. It has excellent resistance to many chemicals including solutions of inorganic acids, alkalis and aliphatic hydrocarbons such as VMP naphtha and heptane. Additionally, it is virtually unaffected by a wide range of commercial products including many beverages, foodstuffs, detergent solutions and cleaners.

PMMA用途

PMMA具有质轻、价廉，易於成型等优点。溶于有机溶剂如苯甲醚等，可以形成良好的薄膜和良好的介电性能，可以作为有机场效应管的介质层。 [1]

它的成型方法有浇铸，射出成型，机械加工、热成型等。尤其是射出成型，可以大批量生产，制程简单，成本低。因此，它的应用日趋广泛，它广泛用于仪器仪表零件、汽车车灯、光学镜片、透明管道。

有机玻璃压克力（亚克力）在建筑业中的应用在建筑方面，有机玻璃压克力（亚克力）主要应用于建筑采光体、透明屋顶、棚顶、电话亭、楼梯和房间墙壁护板等方面；卫生洁具方面有浴缸、洗脸盆、化妆台等产品。在高速公路及高等级道路照明灯罩及汽车灯具方面的应用发展也相当快。其中，建筑采光体、浴缸、街头广告灯箱和电话亭等方面的市场增长较快，今后的发展空间较大，市场前景十分广阔。
