美国首诺 21SPC

Vydyne®  21SPC polyamide 66 Vydyne 21SPC is a general-purpose PA66 resin. ***ailable 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 specificati*** 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 cycle can be reduced because parts may be removed from the c***ity at higher temperatures. In difficult molds where parts h***e a tendency to stick in the c***ity, Vydyne 21SPC can reduce or eliminate the need for mold release sprays. Critical molded-part dimensi*** should be checked against specificati*** before implementing shorter molding cycles on a routine production basis. Typical Applicati***/End Uses: Vydyne 21SPC has been used in many molding applicati*** such as terminal blocks, bearings, bushings, cams, electrical connectors and housings, electrical cable ties/tie straps and many other ha***are and general industrial parts. General Material Status • Commercial: Active ***ailability • Asia Pacific • Europe • North America
