牌号简介	Plexiglas® V825NA是一种热塑性丙烯酸树脂，用于注塑和挤压应用。该等级与Plexiglasv825相同，但不含脱模剂、调色剂或紫外线稳定剂等添加剂。它具有同样的高耐热性和高熔体流动性。Plexiglas® V825NA具有优异的光学性能，使其能够在要求高质量表面外观和/或精密光学的应用中脱颖而出。Plexiglas® V825NA具有良好的热稳定性、挤出熔融强度和良好的工具表面再现性。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® 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.	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.
