2, light, heat preservation and heat insulation: drift beads thin wall hollow, empty cavity for half a vacuum, only trace amounts of the gas (N2 and H2 and CO2, etc.), heat transfer is very slow.So drift beads not only light (250-450 kg/m3 density), excellent heat preservation and heat insulation and thermal conductivity at room temperature (0.08-0.1), which play a prominent role in the field of lightweight thermal insulation material for its laid a solid foundation.
3, high hardness, high strength: because of drift beads on silicon aluminum oxide mineral phases (quartz and mullite) formation of hard vitreous, hardness of Morse 6-7, hydrostatic strength up to 70-140 mpa, true density of 2.10 2.20 g/cm3, therefore, drift beads with high strength.General light porous or insulating materials such as boiling rocks, diatomite, perlite, sea pumice, expanded vermiculite is the difference in hardness, strength is poor, with its system of thermal insulation products or li：建筑裝飾、路面鋪料、屋頂防水保溫涂層、道路工程、改性瀝青等。

3、石油工業(yè)：油田固井、管道防腐保溫、海底油田、漂浮裝置、油井鉆探泥漿減輕劑、石油天然氣輸送管道等方面。

4、絕緣材料：塑料活化填充劑、高溫高壓絕緣體等。

5、涂料工業(yè)：油漆、油墨，粘合劑、隱身涂料、絕緣漆、防腐漆、地坪漆、耐高溫防火漆、內(nèi)外墻涂料、保溫涂料、地板漆、汽車膩?zhàn)印⒃踊业取?br />
6、航天和空間開發(fā)：衛(wèi)星、火箭、飛船表面復(fù)合材料，衛(wèi)星防火層，海洋設(shè)備、船舶、深海潛艇等。

7、塑料工業(yè)：如汽車飾件、儀表板、家電外殼、風(fēng)扇、音箱、燈具總承、鑄件、齒輪、結(jié)構(gòu)件、拉鏈、管材、板材等。

8、玻璃鋼制品：各種玻璃鋼制品、人造大理石、玻璃鋼船舶、工藝品等。only by the rise of temperature, drift beads, on the other hand, increases with the increase of temperature resistance.This advantage is don't have other insulating materials.So, it can make is performance under the condition of high temperature insulation products.
5, particle size, specific surface area: drift beads natural formation of the particle size of 1-250 microns.Specific surface area of 300-360 - g/cm2, and cement.Therefore, drift beads without grinding, can be used directly.Fineness can meet the needs of a variety of products, other lightweight insulation materials generally large particle size (e.g., perlite, etc.), if the grinding would significantly increase capacity, insulating the stays is reduce
