Plexiglas® V825
PMMA(亚克力)
阿科玛Altuglas (Arkema)
产品描述
Plexiglas® V825 is a thermoplastic acrylic resin formulated for injection molding and extrusion applications. It is characterized by its high heat resistance and high melt flow. Plexiglas® V825 has excellent weatherability and optical properties allowing it to excel in applications requiring outdoor stability, high quality surface appearance and/or precision optics. Plexiglas® V825 is easy to process due to its exceptional thermal stability, extrusion melt strength, and excellent tool surface reproduction and release properties. Moldflow simulation data is available. 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.
