Widely used in FRP, composite foams, artificial marble, composite wood, insulation, PuTTY, deep-sea buoyancy materials, bowling, adhesives, sealing materials, lightweight low density resin crafts, mural wall hanging photo frames, wall panels sandwich structure, electronic light packaging materials, absorbing material, light concrete, emulsion explosives, etc.

Artificial marble

Greater use to be made of hollow glass beads marbles. In the United States, many manufacturers are using this kind of filler, it has the following advantages: ① improved impact properties, correct formula products made in its performance above the marble Association requirements. ② improve texture, layout and color of continuity, making the product more beautiful and sparkling. ③ reduce curing time, fast mold-flow rate. ④ improve impact strength, improve the ability to resist cracking, reduce breakage rate. ⑤ to improve machinability, reduced to Flash, cutting, drilling and grinding time. ⑥ reduced tool wear. ⑦ improve light coloring, while reducing the amount of TiO2 (although sometimes mixed in with some darker colors) ⑧ light weight, making it easier during the removal and installation process, reducing transport costs. ③ ~ h of the advantages listed above can significantly reduce costs. Table 1 for artificial marble to standard recipes and hollow glass microspheres used resin viscosity formula for 600~2000cP, with hollow glass beads will not result in increased viscosity of the mixture. Weight in this formula 3.8% of hollow glass beads the size of up to 26.8%, which will make its final weight of 30%. Due to the viscosity of the resin, the ambient temperature and the granularity of the calcium carbonate is the main factor to affect the viscosity of the mixture, so you should optimize these factors make it more smooth texture, bubbles are more likely to exclude, especially when the resin temperature less than 21 ℃.
