由于空心漂珠的质地很轻，堆积密度仅为0.3-0.45克/cm3，无毒、耐腐、耐高温、抗压、绝缘、隔音、导热系数小等优点，主要应用在以下几个方面：1.填料（橡胶、玻璃钢、聚酯塑料） 2.建筑材料 3.油田工业材料 4.涂料和油漆 5.隔音、隔热材料 6.保温、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.
