Detailed Product De
It can improve the performances as strength, temperature resistance, insulation and flame retarding capacity as Inorganic filler
1. Brief Introduction
Silica micropowder is made of natural quartz, with good electromagnetic radiation, extreme-low linear expansion coefficient, good chemical resistance and stability. Its average size is upon your demands from D503 to 40um, and we also can offer surface treatment to improve the performance of Silica micropowder, including compatibility with polymer, hydrophobicity, mechanical properties and mechanical features.
