SABIC has expanded its portfolio of advanced engineering thermoplastics with the launch of its new LNP™ THERMOCOMP™ OFM76XXP and OFM76EXP compounds, specifically engineered for high-voltage, high-power electronic applications. These innovative compounds are based on polyphenylene sulfide (PPS) resin and are designed to meet the demanding performance requirements of modern power electronics, particularly insulated gate bipolar transistor (IGBT) power switching modules.
As electric vehicles, renewable energy systems, and industrial automation technologies continue to operate at higher voltages and power densities, manufacturers require materials capable of delivering enhanced electrical insulation, mechanical durability, and long-term reliability. SABIC's newly developed compounds address these evolving needs by offering exceptional impact strength, excellent dimensional stability, superior thermal shock resistance, and a Comparative Tracking Index (CTI) rated PLC 0, the highest level of resistance against electrical tracking. They also feature excellent dielectric strength for reliable electrical insulation, high heat resistance, and UL94 V0 flame-retardant certification, ensuring enhanced safety in demanding operating environments.
The new materials are particularly suited for applications operating at 800 volts and above, including electric vehicle traction inverters, ultra-fast EV charging systems, renewable energy power converters, robotics, and industrial automation equipment. Their performance characteristics enable manufacturers to design more compact, lightweight, and efficient power modules while maintaining operational safety and durability.
According to Sergi Monros, Vice President of SABIC's Specialties Business, the increasing demand for higher voltages, greater power density, and miniaturized electronic components is encouraging manufacturers to adopt advanced specialty thermoplastics capable of delivering superior stability and long-term performance. He noted that SABIC continues to strengthen its LNP compound portfolio by proactively developing next-generation materials that exceed current industry expectations.
Compared to traditional engineering plastics such as polybutylene terephthalate (PBT) and polyphthalamide (PPA), the new PPS-based compounds provide significantly improved dimensional stability and resistance to repeated thermal shock. They retain approximately 90% of their mechanical strength and insulation properties after 1,000 hours of heat aging at 200°C, demonstrating outstanding long-term durability under extreme operating conditions.
The compounds also support miniaturized product designs by achieving UL94 V0 flame-retardant performance at wall thicknesses as low as 0.4 mm, making them suitable for lightweight electronic assemblies. Additionally, they can be manufactured in white or other light colors, improving the visibility of mandatory QR code markings on electronic components.
SABIC's premium LNP THERMOCOMP OFM76EXP grade further enhances performance with superior laser marking capability, industry-leading impact resistance, improved adhesion to silicone-based sealants, and enhanced crack resistance. Beyond IGBT insulation base plates, these advanced materials are expected to find applications in DC power transmission systems, high-voltage circuit breakers, integrated busbar brackets, renewable energy infrastructure, and other next-generation power electronics. The new compounds are now commercially available worldwide.
Impact on Product
The introduction of SABIC's LNP THERMOCOMP OFM76XXP and OFM76EXP compounds will significantly improve the performance, durability, and safety of high-voltage power modules used in electric vehicles, renewable energy systems, and industrial automation. Their superior electrical insulation, thermal stability, impact resistance, and flame-retardant properties enable manufacturers to produce smaller, lighter, and more reliable power electronic components capable of operating above 800V. Enhanced resistance to thermal aging and mechanical stress extends product lifespan while reducing maintenance requirements. These materials also support advanced manufacturing processes, helping OEMs improve design flexibility, reliability, and efficiency in next-generation electrification technologies.
