产品说明：

Vydyne 21SPC is a general-purpose PA66 resin. Available in natural color. It is designed principally for injection-molding fabrication. This resin offers a well balanced combination of engineering properties characterized by high strength; rigidity; good toughness; high melt point; good surface lubricity; abrasion resistance; and resistance to many chemicals, machine and motor oils, solvents and gasoline.

Vydyne 21SPC permits production of molded parts with good initial color plus good property and color retention when using regrind. This resin is recognized by Underwriters Laboratories and conforms to the requirements of many industrial, federal and military specifications for premium-quality, general-purpose PA66 resins.

Internally and externally lubricated for improved machine feed and exceptional mold release. Vydyne 21SPC is 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 parts have a tendency to stick in the cavity, Vydyne 21SPC 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.

Typical Applications/End Uses:
Vydyne 21SPC has been used in many molding applications such as terminal blocks, bearings, bushings, cams, electrical connectors and housings, electrical cable ties/tie straps and many other hardware and general industrial parts.

Vydyne? 21SPC 物性表

 PA6的化学物理特性和PA66很相似，然而，它的熔点较低，而且工艺温度范围很宽。

它的抗冲击性和抗溶解性比PA66要好,但吸湿性也更强。因为塑件的许多品质特性

都要受到吸湿性的影响，因此使用PA6设计产品时要充分考虑到这一点。为了提高

PA6的机械特性，经常加入各种各样的改性剂。玻璃就是最常见的添加剂，有时为了

提高抗冲击性还加入合成橡胶，如EPDM和SBR等。

对于没有添加剂的产品，PA6的收缩率在1%到1.5%之间。加入玻璃纤维添加剂可以使

收缩率降低到0.3%（但和流程相垂直的方向还要稍高一些）。成型组装的收缩率主要

受材料结晶度和吸湿性影响。

注塑模工艺条件:

干燥处理：由于PA6很容易吸收水分，因此加工前的干燥特别要注意。如果材料是用防水材料包装供应的，则容器应保持密闭。如果湿度大于0.2%，建议在80C以上的热空气中干燥16小时。如果材料已经在空气中暴露超过8小时，建议进行105C，8小时以上的真空烘干。

熔化温度：230~280C，对于增强品种为250~280C。

模具温度：80~90C。模具温度很***地影响结晶度，而结晶度又影响着塑件的机械特性。

对于结构部件来说结晶度很重要，因此建议模具温度为80~90C。
