| Plexiglas® V825NA is a thermoplastic acrylic resin formulated for injection molding and extrusion applications. This grade is the same as Plexiglas®V825 but does not have additives such as mold release, toner or UV-stabilizer. It has the same high heat resistance and high melt flow Plexiglas®V825. Plexiglas® V825NA has excellent optical properties allowing it to excel in applications requiring high quality surface appearance and/or precision optics. Plexiglas® V825NA has good thermal stability, extrusion melt strength, and excellent tool surface reproduction. 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.&& |
