Stanyl 46SF5030, a 30% glass-fiber reinforced super-flow Stanyl grade with UL94 V-0 @ 0.4 mm wall thickness, is characterized by superb processability, exceptional strength and ductility and outstanding weld line strength. Stanyl 46SF5030 is also ideally suited to lead-free soldering processes. It has the required high thermal resistance with the retention of mechanical properties that you expect from Stanyl and it does not blister during soldering at the low wall thicknesses used in these extreme designs. The material is Underwriters' Laboratories (UL) listed and DSM quality procedures make sure of a solid flame retardant performance in all circumstances.

Stanyl 46SF5030 has the same flow as the newest generations of high-flow LCP but with much improved mechanicals in the real-life situation of thin walls and multiple weld lines. Other high temperature polyamides do not even come close:

• Stanyl 46SF5030 enables the molding of the highly complex and thin-walled new generation connectors.
• Productivity with Stanyl 46SF5030 is the same as or even better than LCP's, when using the appropriate runner/sprue dimensions, gate size and position.
• The very high flow of Stanyl 46SF5030 makes filling of multiple cavities easy:
  - Very low injection pressures are required to fill the molds, results in lower tool wear and lower molded in (frozen-in) stresses.
  - Lower pressures result in lower tool repair and maintenance costs.
  - Lower tool temperatures than required with high flow LCP's.
  - Low stress relaxation during soldering, resulting in lower connector deformation.

Enhances design freedom

Stanyl 46SF5030 delivers the best strength and ductility performance (both impact resistance and elongation at break) in actual thin walled connectors. Stanyl also offers a high retention of mechanical properties after lead-free soldering, unlike many competitive materials. This material feature directly influences the failure mode of most advanced connectors:namely pin pull-out in use. Pin pull-out is significantly reduced when Stanyl is used for the insulator material. Stanyl also has excellent creep resistance, so that connectors made with Stanyl maintain their high retention characteristics throughout the useful life of the component.

Excellent weld line strength

Advanced connector designs rely on higher pin densities, so that the weld line count goes up sharply. Stanyl 46SF5030 was developed to give both high flow and excellent weld line strength. The weld line elongation at break and strength of Stanyl 46SF5030 is clearly superior to high-flow LCP. This is an asset during pin insertion in densely pin-populated, low wall thickness connectors. They are more able to withstand the high forces encountered during manual or automated assembly steps, helping to lower reject rates.
