High-Purity Silica Aerogel Powder | Ultra-Low 0.015 W/(m·K) Nano-Insulation

Expert Insights from Ruibin, Lead Technical Consultant at Hebei Woqin

"Aerogel powder isn't just a material; it's a high-performance additive that redefines thermal limits," says Ruibin. "Many clients come to us after failing with low-grade powders that clump or lose hydrophobicity. At Hebei Woqin, we focus on the micro-pore structure. Our powder maintains a 145° contact angle, ensuring that whether it's mixed into mortar or used in EV battery packs, it remains bone-dry and thermally superior for over 10 years."
