NYLON66-Vydyne-21SPC
Vydyne® 21SPC is a general purpose Nylon 66 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, solvents, gasoline, and machine and motor oils
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.
