Reliable solutions for higher Glow Wire Ignition norms

The IEC 60335-1 standard for appliances published in 2001 requires that GWI (glow wire ignition) ratings for appliance connector materials increase to 775ºC on the material or that 750ºC is reached on the end product. This requires polyamide and polyester resins to have more robust flame retardancy than previously.

There are Akulon® PA6 and Arnite® PBT grades that provide this level of security (depending on thickness), with an optimal balance of mechanical integrity and electrical insulation, especially CTI as well as UL (Underwriters Laboratory) approvals for compliance in USA targeted applications. For the highest level of compliance, Stanyl® unfilled and filled flame retardant grades, both normal and high flow series, provide the answer

For non-halogen solutions, Akulon K225-KS meets the GWI requirement and is a halogen-free alternative to PA66 and PBT in appliance connectors. Using halogen-free materials lowers total system costs where applications are covered by the European WEEE directive, as separate post consumer waste stream recycling for halogen containing components are rendered unnecessary.

When appliance connectors are soldered, new concerns can arise. Directives to eliminate heavy metals are driving the change to lead-free solder processes. The higher temperatures required for lead-free solders will cause connector housings made from standard engineering plastics to fail. Stanyl® provides the best solution to all lead-free solder requirements more…

Industrial Connectors:  Akulon PA6 is the proven solution
Industrial connectors are exposed to demanding service conditions and manufacturing flexibility is needed for producers to develop their own unique competitive edge. Akulon PA6 has an extensive track record in meeting these demands, offering:
•  Toughness combined with chemical and electrical resistance to perform
•  Easy processing, coupled with toughness and mechanical strength, gives more design flexibility
•  Reliably and easily colored to meet styling and design requirements

Materials for terminal blocks need toughness and strictly compliant flammability retardant behavior. Especially for terminal blocks that are SMT soldered, the trend to lead-free soldering technology places extra demands on the insulator resin. Stanyl meets this challenge, delivering the lowest system cost components suited to lead-free soldering.
