产品说明：

Vydyne 21SPC is a general-purpose PA66 resin. Available innatural color. It is designed principally for injection-moldingfabrication. This resin offers a well balanced combination ofengineering properties characterized by high strength; rigidity;good toughness; high melt point; good surface lubricity; abrasionresistance; and resistance to many chemicals, machine and motoroils, solvents and gasoline.

Vydyne 21SPC permits production of molded parts with good initialcolor plus good property and color retention when using regrind.This resin is recognized by Underwriters Laboratories and conformsto the requirements of many industrial, federal and militaryspecifications for premium-quality, general-purpose PA66resins.

Internally and externally lubricated for improved machine feed andexceptional mold release. Vydyne 21SPC is intended for use inhigh-productivity applications. In many applications, the moldingcycle can be reduced because parts may be removed from the cavityat higher temperatures. In difficult molds where parts have atendency to stick in the cavity, Vydyne 21SPC can reduce oreliminate the need for mold release sprays. Critical molded-partdimensions should be checked against specifications beforeimplementing shorter molding cycles on a routine productionbasis.

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

1.  食品级认证：食品级PA66塑料是指在生产过程中使用了特定的添加剂和加工工艺，使其满足食品安全要求，不会对人体健康造成危害。这种塑料通过了相关国家和guojibiaozhun的认证，如FDA（美国食品药品监督管理局）和EU（欧洲联盟）等。

2.  加工助剂：在PA66塑料的生产过程中，通常会添加一些加工助剂，如润滑剂、稳定剂等，以确保材料的加工性能和稳定性。这些助剂必须是食品级的，并且不能对人体健康造成危害。

3.  聚合不完全的单体：在PA66聚合过程中，可能会有少量未完全聚合的单体残留。这些单体可能会对人体造成一定的危害，需要严格控制其在产品中的含量。

4.  温度和环境因素：PA66塑料在高温和紫外线照射下容易发生氧化和降解，产生有害物质。在使用过程中需要注意控制温度和避免长时间暴露在阳光下。

食品级PA66塑料在正常条件下使用是无毒的，并且经过了相关认证机构的检测和认可。如果不正确使用或存放，可能会对人体健康造成一定的影响。例如，如果食品级PA66塑料在高温或紫外线照射下长时间暴露，可能会发生氧化和降解，产生有害物质。如果该塑料与食物或饮料接触时发生了刮擦或磨损，也可能会释放出有害物质
