Vydyne®  21SPF (Dry) - Solutia Inc. - 

Vydyne® 21SPF/21SPG are general purpose Nylon 66 resins available in natural color and black. They are designed principally for injection molding fabrication. These grades offer 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. In addition to these attributes, Vydyne 21SPG also offers an enhanced lube package, which is designed for fast cycling and is ideal for use in applications where the part is intended to be decorated during secondary operations, such as vacuum metallization or printing. This mold release package also provides stability during processing, resulting in more efficient cycle times due to the material's moderate level of nucleation and high flow.

Vydyne 21SPF/21SPG Series resins permit production of molded parts with good initial color plus good property and color retention when using regrind. These resins are recognized by Underwriters Laboratories and conform to the requirements of many industrial, federal, and military specifications for premium-quality, general purpose Nylon 66 resins.

Vydyne 21SPF/21SPG Series resins are internally and externally lubricated for improved machine feed and exceptional mold release. They are 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 21SPF/21SPG 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.
