In the automotive industry, construction industry and other applications, often need to avoid a significant reduction in the mechanical properties of plastics on the basis of the original as much as possible to reduce weight and reduce costs. Effective method of reducing the density foamed plastics modification, adding lightweight fillers. The use of azo dimethylamine (AC) chemical blowing agents for foamed plastics modification, can significantly reduce the density of the material, but there are difficult to accurately control the degree of foaming, nonuniform cell structure and other drawbacks, resulting mechanical properties (tensile strength, modulus, etc.) deteriorate.By adding a lightweight filler material way to reduce the weight of these problems can be avoided. Typical lightweight filler is hollow glass beads. This is a powdered inorganic filler, can be taken directly from the glass system, it can also be isolated from coal ash. Its microscopic structure wrapped with a certain amount of gas in the thin-walled, closed microspheres, the relative density is generally 0.4 to 0.7, lower than usual relative density of plastics. Hollow glass microspheres have a smooth spherical surface, it can reduce the weight of the material at the same time, improve mobility and surface quality composites. Hollow glass beads also has a low thermal conductivity, heat resistance, corrosion resistance, and controllable size advantage.

Low density hollow glass beads filled, composite foam density plays a decisive role

Hollow glass beads spherical structure makes the impact force and stress have a good dispersion, added to the paint can well improve the resistance to external impact properties of the film, and the coating can be reduced due to thermal expansion and contraction the stress cracking.
Hollow glass beads is a small density, glass microspheres lightweight, high strength. The main ingredient is Sio2 and Al2o3, because of its unique chemical properties, physical properties, and hollow spherical, compared with ordinary glass beads, light weight, low density, good heat insulation performance characteristics, is thermal insulation coatings the main raw material. Because of its smaller particle size, equal to or greater than the ordinary paint fineness of the filler, which can be added directly to the filler coating systems, the coating having a cured coating film formed by thermal insulation properties.

Hollow glass microspheres Application Features:
There filling performance energy efficient, low low oil, density, added 5% (wt) will be able to make the finished product increased by 25% to 35%, so as not to increase or even reduce the cost per unit volume of the coating. Hollow glass beads particles confined hollow spheres added to the coating formation of many independent microscopic cavity insulation, thus greatly improving the coating on the thermal and sound insulation, play a very good thermal insulation and noise reduction effect. The coating has a more waterproof, anti-fouling, corrosion resistance. When the surface of the hollow glass microspheres are chemically inert chemical resistance, as the film tightly packed particles of glass beads, the formation of low porosity, the coating formed on the surface of the moisture and corrosion caused by the blocking effect of ions protective film, played well protective effect.

Traditional buoyancy materials generally use polyurethane foam, epoxy foam or other foam plastic, although the cost is low, but the pressure strength is low, soaking for some time, will lose water buoyancy, the use of poor reliability. People began to develop lightweight high-strength solid buoyancy materials to replace the traditional buoyancy materials for deep-sea resource exploration and mining.
At present, the use of high-performance hollow glass beads filled with polymer synthesis of deep-sea high-strength buoyant material has been applied. It is made of epoxy resin
