由于空心漂珠的質地很輕，堆積密度僅為0.3-0.45克/cm3，無毒、耐腐、耐高溫、抗壓、絕緣、隔音、導熱系數(shù)小等優(yōu)點，主要應用在以下幾個方面：1.填料（橡膠、玻璃鋼、聚酯塑料） 2.建筑材料 3.油田工業(yè)材料 4.涂料和油漆 5.隔音、隔熱材料 6.保溫、耐火材料

As the quality of cenospheres is very light, the bulk density is only 0.3-0.45g/cm3, and It has the advantages of non-poisonous、acid resistanc、high temperature resistance、resist- compression、insulation、sound insulation、little heat conductivity. It is mainly
used in these fields : 1.additives (rubber、glassfiber、polyester plastics) 2. building materials 3. oil field industrial materials 4. coating & paint 5. sound and heat insulation 6. insulation and refractory materials.
