Major R&D Breakthrough | New-Generation Epoxy Insulating Material for High-Frequency Transformers

Shanghai Xrun has achieved a key R&D breakthrough with a new customized epoxy insulating material for high-frequency scenarios. The material features an ultra-low dielectric loss of below 0.2%, which fundamentally reduces dielectric heat generation. With a thermal conductivity of 1.2–2.0 W/(m·K), it efficiently dissipates internal heat and restrains temperature rise. Combined with high Tg and superior electrical insulation properties, it maintains stable insulation reliability under harsh conditions of high temperature, high frequency and strong electric fields, effectively mitigating thermal aging failure risks.
