Nano gold colloids with good stability

Our client said Nano colloidal gold and gold nanoparticles of Hongwu are unrivaled – we found that your company the best that we could work with.”

Colloid gold solution possesses unique properties such as good optical characteristics, biocompatibility, and catalytic activity. 

In high crystallinity matrix resin, adding materials with high thermal conductivity is the most effective method to improve plastic thermal conductivity.The thermal conductive filler is refined and even nano size is made, which not only has little effect on mechanical properties, but also improves thermal conductivity. With the addition of nanometer magnesium oxide Magnesia Nanoparticles of high purity, good whiteness, small particle size and uniform particle size, the thermal conductivity is made up of ordinary 33W/(m).K) raised above 36W/(m. K). It can be used in PA, PBT, PET, ABS, PP, organic silicone, coating and other materials to play the role of thermal conduction. Thermal conductive agent: this product has excellent thermal conductivity, suitable for thermal interface materials, such as thermal plastic, thermal resin castable, thermal silicone, thermal powder coating, functional thermal conductive paint and various functional polymer products. The thermal conductivity can reach 3.4w/m.k. when 80% high-purity nanometer magnesium oxide is added into PPS. When 70% aluminum trioxide is added, the thermal conductivity can reach 2.392W/m.K. Notice: Nano Materials have lots of applications that we canot list one by one. And the applications we listed is theorically available according to characteristics of certain Nano Material and researches. For practical applications we would strongly advise you to have sample for testing. Thanks. 

There are three kinds of common copper powder morphology: spherical, flaky and dendritic. Ultrafine dendritic copper powder is a kind of dark brown metal powder, which is widely used in catalysis, electrode materials, copper paste fillers, microelectronics industry and printed electronics technology

Nano palladium powder can be used as a good hydrogen storage material. On the other hand, nano-palladium powder is an indispensable material for thick film conductive paste.

Hongwu Nano supply various Silver coated Copper powder for different application

We could do nano silver wires at smaller diameter <60nm, with high electrical conductivity.

Antimony Tin Oxide (ATO) Nanopowder / Nanoparticles without element chlorine can be manufactured in the form of solid powder and agueous dispersion.

Flake silver conductive powders has 1-2um or 3-8um particle size, widely used in low temperature conductor paste.
