LANXESS is expanding its polybutylene terephthalate (PBT) -based halogen-free flame retardant compound product line to include variants with excellent fire resistance in the glow wire test. The first new product is a 25% glass fiber reinforced composite. There are plans to bring trial products to market in the short term.
Alexander Radeck, an application development expert in the LANXESS Performance Materials (HPM) business unit, explains: "Due to its high glow-wire resistance, this PBT material has great potential for use in unattended home appliance components. In addition, we We see great opportunities in the electrical and electronic components of electric vehicles, such as in the field of battery charging. "
The new PBT material is certified by the German VDE testing and certification agency GmbH (VDE Prüf-und Zertifizierungsinstitut GmbH), with a GWIT value of 775 ° C and a wall thickness of 0.4 to 3.0 mm (glow wire ignition temperature, IEC 60695-2-13). It has also achieved good results in the glow wire test of IEC 60695-2-11 finished parts. "Thus, we believe that this material also performs well in the glow wire test of the more stringent finished parts of IEC 60335-1 unattended appliances, and can be used in parts of washing machines, dishwashers and tumble dryers. In such applications, this compound has higher electrical trace resistance than halogen-containing flame retardant materials. "
