Hollow Microsphere (Hollow Glass Microsphere) is small hollow round ball form powder. Grain size is between 1-500 microns, the density is in the 0.1-0.3 g/cm3.Having light weight and big volume, low transmit heat coefficient , high anti- press strength ,and having good dispersion, mobility, the stability. Moreover also having good insulativity, self-lubricating, soundproof, don’t absorb water, fire-proof, corrosion resistance, radiation protection, non-toxicity,etc. excellent function. This product could direct fill in many resin product of thermoset, thermoplastic. It could reduce product’s weight, cut down producing cost, eliminate product’s internal stress,etc. And also could substitute some of bronze powder, molybdenum disulfide and White Carbon etc. some expensively fill material.
Hollow Glass Microsphere is component of inorganic material. The chemistry composition include:SiO2, Al2O3, ZrO.2., MgO, Na2Si2O5 etc. Its grain size from 10 to 500 microns, wall thickness only have a few micron.
