The LE-9229/LH-9229 epoxy resin system is a dual-component, modified rubber-toughened formulation designed for demanding electrical insulation applications. Combining LE-9229 epoxy resin and LH-9229 hardener at a precise 1:1 ratio (100 pbw each) with silica flour filler (280-340 pbw), this system delivers exceptional thermal stability (Tg 105-125°C), crack resistance, and mechanical strength. Ideal for medium/high-voltage insulation (10-35kV), it supports both automatic pressure gelation (APG) and vacuum casting processes, making it suitable for transformers, solid-pole bushings, and switchgear components.
