Selar® PA 3426是一种无定形尼龙(聚酰胺)树脂,具有优越的透明度,对气体、水、溶剂和精油具有良好的阻隔性能,以及高温结构性能,使其适用于多种应用。特点:Selar® PA 3426阻隔树脂既可用于软包装结构,也可用于硬包装结构,具有很好的气体O2、CO2和防潮性能。此外,SELAR PA的独特之处在于其气体屏障随着相对湿度的增加而改善。它具有优良的物理性能、耐高温性和结构树脂所需的优良光学性能。与其他尼龙一样,Selar-PA阻隔树脂对许多类型的溶剂系统是一种很好的阻隔。一般来说,它对脂肪族、芳香烃、稀碱、高分子量醇和低浓度低分子量醇具有良好的抗性。不建议用于酸或浓缩的低分子量醇。建议对每个应用程序进行最终使用测试。SELAR PA具有很高的硬度、很好的气体和防潮性、耐溶剂性和极好的光泽度和透明度,用于单层包装,为刚性包装提供了“玻璃状”容器。应用:高熔体粘度的挤出过程,如电子束。与尼龙6混合后,在收缩应用中的性能得到改善。单层吹塑管,药瓶或瓶子,通常少于4盎司。尼龙6改性具有更高的耐热性、更好的氧阻隔性、更宽的热成型窗口。 Selar® PA 3426 is an amorphous nylon (polyamide) resin which exhibits superior transparency, good barrier properties to gases, water, solvents and essential oils and high temperature structural properties which make it suitable for consideration in a number of applications. Features: Selar® PA 3426 barrier resin can be utilized in both flexible and rigid packaging structures and is characterized by very good gas O2, CO2 and moisture barrier. Furthermore, Selar® PA is unique in that its gas barrier improves with increasing relative humidity. It has excellent physical properties, high temperature resistance and excellent optical properties desirable in a structural resin. Like other nylons, Selar® PA barrier resin is an excellent barrier for many types of solvent systems. In general it has good resistance to aliphatic, aromatic hydrocarbons, dilute alkalis, higher molecular weight alcohols, and low concentrations of lower molecular weight alcohols. It is not recommended for acids or concentrated lower molecular weight alcohols. End use testing is recommended for each application. With its high degree of stiffness, very good gas and moisture barrier, solvent resistance and excellent gloss and clarity, Selar® PA used in monolayer provides a "glass like" container for rigid packaging. Applications: High melt viscosity for extrusion processes such as EBM. Improved performance in shrink applications when blended with nylon 6. Monolayer - blow molded tubes, pharmacuetical vials or bottles, typically less than 4 ounces. Nylon 6 modification for higher heat resistance, better oxygen barrier, broader thermoforming window. |
