Weather resistance is obtained by incorporating finely divided, well-dispersed carbon black particles in the nylon matrix. While the presence of carbon black usually increases brittleness, these resins have been formulated to minimize loss of ductility properties such as elongation and Izod impact strength. As a result, parts molded from 25WSP frequently exhibit higher ductility and practical toughness compared with other black, weather resistant, non-impact modified nylon 6,6 molded parts.
Vydyne® 25WSP resins are internally and externally lubricated for improved machine feed and exceptional mold release. Vydyne® 25WSP is intended for use in high-productivity applications. In many applications, the molding cycle can be reduced because molded parts may be removed from the cavity at higher temperatures. In difficult molds where parts have a tendency to stick in the cavity, Vydyne® 25WSP 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.
Application End Uses
Lubricated for machine feed and mold release, Vydyne® 25WSP provides very good flow and easy moldability. Typical applications include cable ties/tie straps, where its combination of easy flow, good ductility, and high tensile strength is particularly attractive, and a wide variety of electrical/electronic and miscellaneous applications requiring weather resistance.
