Vydyne® 20NSP is a general-purpose, highly nucleated nylon 6,6 resin with internal and external lubricant. It is designed to crystallize rapidly when cooled from the molten state. This rapid crystallization can result in reduced cycle times and increased productivity through faster part setup when compared with standard general purpose nylon 6,6 resins. The crystalline structure resulting from nucleation will alter part properties, yielding increased modulus or rigidity, increased tensile strength, reduced elongation, reduced impact strength and mold shrinkage compared with standard general-purpose nylon 6,6.
The Vydyne 20NSP series resins have an internal lubricant for improved machine feed and mold release. This formulation is designed to provide easy release of parts from molds using standard molding conditions. The rapid crystallization of Vydyne 20NSP resins may allow part ejection at higher temperatures compared with general-purpose nylon 6,6. This will reduce the mold closed time and thereby decrease the molding cycle. Critical factors unique to each application such as mold/part design, tolerances, etc., may negate these cycle time benefits. It is recommended to check critical part dimensions against specifications before implementing shorter molding cycles on a routine basis.
Typical end uses for Vydyne 20NSP are terminal blocks, bearings, business control cams, electrical connectors, housings, wire ties, fasteners, switch components, and general industrial parts that require stiffness and rigidity.
