| Plexiglas® V825-HID is a thermoplastic acrylic resin formulated for injection molding and extrusion applications. It is specifically formulated for UV-emitting light or High Intensity Discharge sources up to 90C. It is characterized by its excellent ultra-violet, heat resistance and high melt flow. Plexiglas® V825-HID 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-HID 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. |
