TOPAS 具有与PMMA（聚甲基丙烯酸甲酯、丙烯酸树脂）相匹敌的光学性能以及具有高于PC（聚碳酸酯）的耐热性，还由于低吸水性而具有比PMMA和PC更加优良的尺寸稳定性等，在市场上获得了很高的评价。再有，TOPAS还具有改善水蒸汽气密性，增加刚性、耐热性，能赋予易切割性等优点，作为适合于用作传统材料的改性用材料，它在包装材料领域里的开发活动正在推进之中
优良的光学性能：具有能与PMMA相匹敌的光学性能和与PC同等或超过它的耐热性，还由于它几乎不吸水，因而还是具有高度的尺寸稳定性等优良的性能的树脂，它在光学市场领域获得了很高的评价
Product Description
TOPAS 8007F-04 is a general purpose film extrusion grade. It is a high clarity amorphous resin with high stiffness, moisture barrier, chemical resistance, thermoformability and purity for food and healthcare applications. It is used in monolayer cast applications, and in coextrusions in both cast and blown processes, for a wide variety of film and sheet products requiring excellent optics in applications such as blister, twist, barrier, shrink and easy tear packaging. Industrial uses include formed decorative sheet products. For property enhancement at elevated temperatures, higher glass transition temperature (Tg) grades of TOPAS are recommended.
