• LANXESS expands its range of flame retardant plastics;
• VDE certified materials for glow wire testing on the final product;
• High flame resistance offers greater freedom in component design;
• Potentially suitable for electric vehicles.

The demand for home appliances also remains strong as many consumers increasingly invest in their own four walls. The result is a growing demand for flame retardant plastics that meet the international fire resistance standard IEC / EN 60335-1 for components of unattended household appliances such as dishwashers. In response, LANXESS is expanding its line of flame retardant compounds to include material variants that provide a high degree of flame resistance in glow wire tests performed in accordance with this standard.

The latest addition to this range is the flame retardant and halogen-free Durethan BKV30FN34, which is primarily aimed at users who, for safety reasons, prefer to test the glow wire on the final product in accordance with the strict conditions and requirements of the standard for household appliances. (Glow wire end product test, IEC 60695-2-1). “This blend of polyamide 6 offers enormous safety reserves thanks to its high degree of flame resistance. This opens up more freedom in the geometric design of the components, ”explains Alexander Radeck, flame retardant plastics expert in the High Performance Materials (HPM) business unit.
High resistance to leakage current and elongation at break

The glow wire resistance of this new polyamide 6 has already been certified by VDE Pruef- und Zertifizierungsinstitut GmbH (German Association for Electrical, Electronic and Computer Engineering) with a GWIT value of 775 ° C for wall thicknesses between 0.4 and 3.0 millimeters (Glow wire ignition temperature, IEC 60695-2-13). Another advantage of this material is its high tracking resistance of 600 V (CTI A, Comparative Tracking Index, IEC 60112), which reduces the risk of short circuits and faults caused by leakage currents. This allows designers to make electrical and electronic modules more compact, thereby reducing the size of the final product. The plastic, which is reinforced with 30% by weight short glass fibers, also offers high elongation at break. “This means that snaps, for example, which are a bit thicker for visual reasons, don’t warp or break before they snap into place,” says Radeck.

Another PBT compound with exceptional resistance to glow wire
Another compound designed for glow wire testing on the final product is Pocan TFN4230. The PBT + PET (polybutylene / polyethylene terephthalate) blend is already used in a range of serial applications and has been certified by VDE with a GWIT value of 775 ° C (0.4-3.0 millimeters). The material not only offers high resistance to tracking, but also exceptional dimensional stability.

Potential for application in vehicle battery charging systems
Radeck: “We want to see these two compounds used in housings, microswitches and connectors for devices such as washing machines, dryers and dishwashers. But we also see exciting potential in a range of electrical and electronic components for electric vehicles, particularly in battery charging systems. “
