Vydyne® 21X1是一种通用的PA66树脂。它是天然的,主要为注塑应用而设计,在注塑过程中改善了流动性。21x1具有相同的良好平衡的工程性能组合,具有高强度、刚性、良好韧性、高熔点、良好的表面润滑性、耐磨性和耐多种化学品、机器和机油、溶剂和汽油的性能。Vydyne® 21X1树脂允许生产具有良好初始颜色和良好性能和使用再研磨时保持颜色的成型零件。该树脂经保险商实验室认可,符合许多工业、联邦和军用优质通用PA66树脂规范的要求。Vydyne® 21X1为外部润滑,用于高生产率应用。在许多应用中,由于零件可能在较高温度下从型腔中取出,因此可以缩短成型周期。在零件容易粘在型腔中的困难模具中,Vydyne® 21X1可以减少或消除模具释放喷剂的需要。在常规生产基础上实施较短的成型周期之前,应根据规范检查关键的成型零件尺寸。典型应用/最终用途:Vydyne® 21X1树脂已用于许多成型应用,如接线板、轴承、衬套、凸轮、电气连接器和外壳、电缆扎带/扎带以及许多其他硬件和一般工业零件。 Vydyne 21X1 is a general-purpose PA66 resin. Available in natural, it is designed principally for injection-molding applications with the added benefit of improved flow during the molding process. 21X1 offers the same 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 21X1 resin 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. Vydyne 21X1 is externally lubricated and 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 21X1 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 21X1 resin 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. |
