Plexiglas® V825UVA是一种热塑性丙烯酸树脂,用于注塑和挤压应用。它是为需要特定紫外线传输要求的特殊照明组件而制定的。Plexiglas® V825UVA具有优异的耐候性和光学性能,使其能够在要求室外稳定性、高质量表面外观和/或精密光学的应用中脱颖而出。Plexiglas® V825UVA因其优异的热稳定性、挤出熔融强度和良好的工具表面再现和释放性能而易于加工。它对无机酸、碱和脂肪族碳氢化合物(如vm&p石脑油和庚烷)的溶液具有优异的抗药性。此外,它几乎不受各种商业产品的影响,包括许多饮料、食品、清洁剂溶液和清洁剂。 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. |
