DuPont Packaging & Industrial Polymers

产品说明

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.

特性: 尼龙作为大用量的工程原料,广泛用于机械.汽车.电器.纺织器材.化工设备.航空等领域。
成为各行业中不可缺少的结构材料，其主要特点如下：
1 优良的力学性能。尼龙的机械强度高韧性好。
2 自润性，摩擦性好。尼龙具有很好的自润性摩擦系数小，作为传动部件其使用寿命长。
3 优良的耐热性。如尼龙46等高结晶性尼龙的热变形温度很高，可在150℃下长期使用。PA66经过玻璃纤维增强以后，其热变形温度达到250℃以上
4 的电绝缘性能。尼龙的体积电阻很高，耐击穿电压高，是优良的电气，电器绝缘器材。
5 优良速度耐气候性。
6 吸水性。尼龙吸水性大，饱和水可达到3%以上。在一定程度影响制件的尺寸稳定性。
应用： 尼龙主要用于汽车配件、电气装置、交通运输业、机械制造工业、电线电缆通讯业、薄膜及日用品。
