Plexiglas® V825UVA
PMMA(亚克力)
阿科玛Altuglas (Arkema)
产品描述
Plexiglas® V825UVA is a thermoplastic acrylic resin formulated for injection molding and extrusion applications. It is formulated for specialty lighting packages requiring specific UV transmission requirements. Plexiglas® V825UVA has excellent weatherability and optical properties allowing it to excel in applications requiring outdoor stability, high quality surface appearance and/or precision optics. Plexiglas® V825UVA 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 VM&P naphtha and heptane. Additionally, it is virtually unaffected by a wide range of commercial products including many beverages, foodstuffs, detergent solutions and cleaners.
