产品说明：

vydyne 21spc is a general-purpose pa66 resin. available innatural color. it is designed principally for injection-moldingfabrication. this resin offers a well balanced combination ofengineering properties characterized by high strength; rigidity;good toughness; high melt point; good surface lubricity; abrasionresistance; and resistance to many chemicals, machine and motoroils, solvents and gasoline.
vydyne 21spc permits production of molded parts with good initialcolor plus good property and color retention when using regrind.this resin is recognized by underwriters laboratories and conformsto the re of many industrial, federal and militaryspecifications for premium-, general-purpose pa66resins.
internally and externally lubricated for improved machine feed andexceptional mold release. vydyne 21spc is intended for use inhigh-productivity applications. in many applications, the moldingcycle can be reduced because parts may be removed from the cavityat higher temperatures. in difficult molds where parts have atendency to stick in the cavity, vydyne 21spc can reduce oreliminate the need for mold release sprays. critical molded-partdimensions should be checked against specifications beforeimplementing shorter molding cycles on a routine productionbasis.
typical applications/end uses:
vydyne 21spc has been used in many molding applications such asterminal blocks, bearings, bushings, cams, electrical connectorsand housings, electrical cable ties/tie straps and many otherhardware and general industrial parts.
