Overview of Hollow Glass Microspheres
The Hollow glass microsphere is a hollow spherical powdery ultra-light inorganic non-metallic material, which has the characteristics of light weight, large volume, low thermal conductivity, high compressive strength, and dispersion. It has the characteristics of strong sex and, fluidity and good chemical stability. The positive spherical shape can produce better results than traditional fillers. It can replace traditional materials such as silica, calcium carbonate, talcum powder and clay in many fields. It is easier to mix with compounds so that it can be used in various production processes, such as spraying, casting and moulding. A high-performance filler for SMC\BMC and other thermoplastics and thermoset elastomers.
Features of Hollow Glass Microspheres
Hollow glass microspheres are tiny spheres. In fluid, like mini sphere bearings, they have better fluidness than sheet-like, needle-like or irregular-shaped fillers. The resulting microsphere effect makes The thickness of the mixture decrease, and the mold and mildew filling up performance is naturally outstanding; the great handling performance can raise the manufacturing performance by 10% to 20%.
The ideal spherical shape makes it have the smallest details surface, so its oil absorption is low. Compared with the standard loading material calcium carbonate, the oil absorption price of hollow micro-bubbles is much lower, which minimizes the quantity of resin. At the same time, it can play the function of raising the fluidness of the resin to ensure that the resin is just refined as a base material instead of a filler, thereby decreasing the quantity of material used.
The hollow micro-bubbles are a vacuum cleaner and slim gas. The density and thermal conductivity of the two various products are various, so it has the attributes of sound insulation, heat insulation, and reduced thermal conductivity. It is excellent as a selection of warm conservation and audio insulation items. Filler. The insulating homes of the microspheres can likewise be used to secure items from thermal shock brought on by rotating between swiftly heating and quickly cooling conditions.The closed area rate is extremely high, the round shape is limited and excellent, and it is insoluble in water, making its application in water very secure. Water will not enter the inside of the microspheres, so it will certainly not cause the resulting increase in thickness. It is suitable for water, and its application in water, such as luxury yachts and rowing boats, is also exceptionally steady.
