Hollow glass microspheres micro spheres bubbles beads
Hollow glass microsphere is a tiny sphere with high ball-type rate. Its ball-bearing effect can
improve its mobility and reduce the viscosity and internal stress of resin mixture.
It is also called flying ash hollow ball, grayish white, thin wall and hollow, very light weight.
It has fine grain, hollow, light weight, high strength, wear resistance, high temperature resistance, insulation, flame retardant insulation and other properties, is widely used in one of the refractory raw material industry.

Product Features
The color is good. The appearance is pure white like calcium carbonate, which can be widely used in products of any color.
Light weight and large volume. After filling and application, the weight of the product can be greatly reduced, thereby reducing the amount of the main raw material resin and reducing the product cost.
The filling process is simple. The hollow glass beads do not require surface treatment, and can be directly mixed with the main raw material or made into a master batch. Products filled with hollow glass microspheres are lighter in weight, larger in volume, and better in various physical and mechanical properties than products filled with other fillers.
The fluidity is good, and the product size is extremely stable. Because the hollow glass beads are tiny spheres, they act like another product produced by Zhaotong in liquid, and they have better fluidity than the filling particles of flake, needle or irregular shape. , The resulting microsphere effect reduces the viscosity of the mixed material, naturally excellent mold filling performance, and good processing performance, which can increase the production efficiency by 15%-20%. Since the spherical object is isotropic, the filled beads will not cause the inconsistent shrinkage rate of different parts due to orientation, which ensures the dimensional stability of the product and does not warp, and solves the problem of forming special profiles and large injection products. Processing long-standing deformation problems.
Heat insulation, sound insulation, insulation, low water absorption rate. The inside of the hollow glass beads is a thin gas, so it has the characteristics of sound insulation and heat insulation, and is an excellent filler for various heat preservation and sound insulation products. The thermal insulation properties of hollow glass microspheres can also be used to protect products from thermal shocks caused by alternate changes between rapid heating and rapid cooling conditions. The high specific resistance and extremely low water absorption make it widely used in the processing and production of cable insulation materials.
It can improve the physical and mechanical properties of plastic products. Increase the processing performance of plastics, while improving the surface leveling of engineering plastics. The isotropy of hollow microspheres or solid microspheres can solve the surface of glass fiber reinforced
Application areas:
FRP hollow glass microspheres are used in FRP to reduce the weight of the product, facilitate processing and manufacture, and enhance the rigidity, impact strength and bending strength of the product. Improve its chemical stability, make the product size stable, have good reprocessing performance, easy to cut, drill, nail, etc. In addition, the amount of expensive resin can be reduced and the cost can be reduced. These lightweight products are widely used in various industrial fields, such as vehicles, ships, construction sandwich composite panels, sports equipment, models, etc.
Composite materials for repairing (putty) Composite materials for repairing. The typical application is to add hollow glass beads to the resin to replace some fillers such as calcium carbonate and talc to make various putties. The finished products are light in weight and attached. Strong focus, easy application, low shrinkage, good stability, etc. In addition, the curing time can be shortened, especially the processing performance such as sanding and polishing can be significantly improved. This putty can completely replace expensive imported putty, and is widely used in repairing various vehicles, especially high-end cars, ships, and machine tools.
The application of artificial marble and synthetic wood to artificial marble can greatly reduce the weight of the product, improve its anti-cracking performance, smooth and beautiful appearance, and reduce cost. Used in synthetic wood, finished products have the same texture and structural properties as wood. The products are mainly used for high-end sanitary ware, furniture castings, decorative panels and light-weight flooring for vehicles.
