SABIC has launched two grades of polyphenylene sulfide (PPS) compounds constructed to insulate high-voltage energy modules, together with the insulated-gate bipolar transistor (IGBT) switching units utilized in electrical drive techniques. The brand new LNP THERMOCOMP OFM76XXP and OFM76EXP compounds have the potential for use in energy modules for 800 V and better traction inverters and quick chargers, in addition to renewable vitality techniques and industrial automation similar to robotics.
Each grades carry a comparative monitoring index (CTI) of PLC 0, the best CTI class, together with dielectric energy for electrical insulation and UL94 V0 flame retardancy all the way down to a 0.4 mm wall thickness. SABIC says the compounds retain 90% of their energy and insulation functionality after 1,000 hours of warmth growing older at 200° C. In contrast with polybutylene terephthalate (PBT) and polyphthalamide (PPA) supplies, the corporate says they provide higher dimensional stability and resistance to thermal shock, supporting thinner and lighter elements. They can be molded in white or mild colours so the QR codes printed on IGBTs keep seen.
PPS resins face up to steady warmth and resist monitoring, the floor breakdown that may kind conductive paths throughout an insulator at excessive voltage. Each properties matter in 800 V energy electronics, the place increased voltages and denser packaging stress the insulating supplies.
The OFM76EXP grade affords enhanced laser-marking functionality, adhesion to silicone-based sealants and crack resistance, and SABIC says it has the best affect energy of the comparable supplies.
Past IGBT module insulation base plates, SABIC lists potential makes use of in DC energy transmission techniques, high-voltage inverters and breakers, built-in busbar brackets and renewable vitality infrastructure. Each grades can be found globally.
“Greater voltages, higher energy densities and miniaturization are driving producers of important energy digital units like IGBT switches to decide on supplies that assist improve stability and energy,” stated Sergi Monros, SABIC’s Vice President of the Specialties Enterprise.
