As one of China’s earliest nanoparticles manufacturer, HONGWU has developed four product series: metal nanoparticles ( Ag, Pt, Pd, etc ), oxide nanoparticles ( Cu2O, TiO2, etc), carbon family nanoparticles ( MWCNT, C60, etc) and compound nanoparticles ( SiC, B4C ). Particle size range from 10nm-10um, and different product and specification may has different morphology. For within 200nm Ag, we have spherical morphology, for micron size, both spherical morphology and flake morphology are available and offered in 99.99% high purity, also silver nanorod, silver nanowires are available. Our company entered the nanoparticles material since 2002, decades of experience in this industry created our mature and reliable technicians team, quality and stable supply for both retail and batch orders are assured, special needs like specific SSA, special particle size, certain surface treatment, water dispersions to avoid disperse issue, etc can be met; rich experience also helped developed trustful partners, shipping partners-regular goods, dangerous goods, air shipping, express shipping, we could always export and deliver goods to our customers; testing partner-authorized testing centers to arrange necessary tests and certificates if needed. The product will supply to all over the world, such as Europe, America, Australia,Nicaragua, Salt Lake City,Mexico, Holland.Customized & ISO certified & Factory prices & Worldwide shipping.
