Characteristics of hollow glass microspheres
Hollow glass microspheres are composed of inorganic materials. According to the chemical composition are silica, alumina, zirconia, magnesium oxide, sodium silicate and so on. With sizes ranging from ten to a few hundred microns, they are enclosed microspheres filled with CO2 gas. It has the advantages of lightweight, low thermal conductivity, non-toxic, non-combustible, good chemical stability, high dispersion and so on. It is an excellent product filler for artificial marble, glass-reinforced plastic, putty, paint, plastics, explosives, chemical industry, building materials and other industries.
The color white
Can be widely used in any appearance color requirements of the products.
The proportion of light
The density of hollow glass microspheres is about one-tenth of the density of traditional filling material particles. After filling, it can greatly reduce the base weight of the product, replace and save more resin for production and reduce the cost of the product.
lipophilicity
Hollow glass microspheres are easy to wetting and dispersing, and can be filled in most thermosetting thermoplastic resins, such as polyester, epoxy resin, polyurethane, etc.
Liquidity is good
Because hollow glass microspheres are tiny spheres, they have better fluidity than flakes, needles or irregular fillers in liquid resin, so the filling performance is excellent. More importantly, this kind of microsphere is isotropic, so it will not produce the disadvantage that the shrinkage rate of different parts is not consistent due to the orientation, which ensures the size stability of the product and will not warp.

Heat insulation and sound insulation
Hollow glass microspheres inside are thin gas, so it has the characteristics of sound insulation, heat insulation, is as a variety of heat preservation, sound insulation products excellent filler. The thermal insulation properties of hollow glass microspheres can also be used to protect the product from thermal shock caused by alternating changes between acute heat and acute cold conditions. High specific resistance and very low water absorption make it widely used in cable insulation material processing.
The oil absorption rate is low
The particles of the sphere determine its minimum specific surface area and low oil absorption rate, the use of the process can greatly reduce the amount of resin, even in the premise of the high amount of viscosity will not increase a lot, greatly improve the production operating conditions, can make the production efficiency increased by 10% ~ 20%.
