Vydyne® 21SPF

Technical Datasheet | Supplied by Ascend Performance Materials

Vydyne® 21SPF by Ascend Performance Materials is a general purpose, unfilled polyamide 66 (PA 66) resin with an enhanced crystallization temperature. It is suitable for injection molding fabrication.

It offers high strength & rigidity, good toughness, high melt point, good surface lubricity, abrasion resistance and resistance to many chemicals, machine & motor oils, solvents & gasoline.
It permits production of molded parts with good initial color plus good property and color retention when using regrind.
Vydyne® 21SPF is internally and externally lubricated for improved machine feed and exceptional mold release. The molding cycle can be reduced in many applications.
It exhibits fast molding cycle.
It is used in bearings, bushings, cams, connectors, electrical housing, electrical/electronic applications, fasteners, housings and industrial applications.
