| Plexiglas® VSNA is a thermoplastic acrylic resin formulated for injection molding applications. This grade is the same as Plexiglas®VS but does not have additives such as mold release, toner or UV-stabilizer. It is characterized by its very high melt flow. Plexiglas® VSNA excellent optical properties allowing it to excel in applications requiring high quality surface appearance and/or precision optics. Plexiglas® VSNA is easy to process due to its exceptional thermal stability 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.&& |
