产品说明
Vydyne 22HSP is a heat stabilized molding grade Nylon 6,6 resin available in natural color and black. It is lubricated for improved machine feed and mold release and is intended for use in applications requiring fast molding cycles and outstanding mold release performance. The stabilization package has been formulated to provide improved retention of physical and electrical properties, compared to non-heat stabilized grades during long term exposure to high temperatures.
Vydyne 22HSP Series offer a well balanced combination of engineering properties characterized by high strength, rigidity, good toughness in use, high melting point, good surface lubricity, and abrasion resistance. In addition, it is resistant to many chemicals and solvents, including gasoline, and machine and motor oils.
Internally and externally lubricated for improved machine feed and exceptional mold release. Vydyne 22HSP Series are intended for use in high productivity applications. In many applications, the molding cycle can be reduced because parts may be removed from the cavity at higher temperatures. In difficult molds where Vydyne 22HSP Series resins can reduce or eliminate the need for mold release sprays. Critical molded part dimensions should be checked against specifications before implementing shorter molding cycles on a routine production basis.

PA66美国首诺9
聚酰胺俗称“尼龙”，英文简称PA，目前它为最大的通用工程塑料品种。PA包括种类
很多，具体可命名为PAxy，其中x代表二元胺的碳原子数目，y代表二元酸的碳原子数目。适用于塑料用的PA主要是脂肪族PA和少量芳香族PA。具体品种有PA6、PA66、PA610、PA1010、PA11、PA12、PA9、PA612、PA46、PA1212、浇铸尼龙（MC5）及芳香尼龙等。其中PA6占47%，PA66占45%。
PA目前最大的应用为汽车配件，美国占30.7%，西欧占31.6%，日本占34.5%。其他用途有包装膜、电子电器、机械零件、日用品等。
1、 酰胺塑料的性能
（1）一般性能 PA的外观为透明或不透明乳白色或淡黄色的粒料，表观角质、坚硬，制品表面有光泽。 PA的吸水率比较大， 酰胺基的比例越大，吸水率越高，具体为：
PA6＞PA66＞PA610＞PA1010＞PA11＞PA12＞PA1212。PA属于自熄性塑料，燃烧时有烧焦的羊毛或指甲味。PA属中等阻隔性塑料，阻隔性随酰胺基/亚甲基的比例增大而提高，以PA6的阻隔效果最好。PA6的O2透过系数为25～40㎝3?㎜/㎡?d?Mpa
