Hollow glass beads

Hollow glass microspheres are specially processed glass beads, which are characterized by lower density and poorer thermal conductivity than glass beads. It is a new kind of micron grade light material developed in the 1950s and 1960s. Its main component is borosilicate, with a general particle size of 10~250μm and a wall thickness of 1~2μm. Hollow glass beads are characterized by high compressive strength, high melting point, high resistivity, small thermal conductivity and thermal shrinkage coefficient, etc., and they are known as the "space-age material" in the 21st century. Hollow glass beads has obvious weight and sound insulation heat preservation effect, make the products have very good crack resistance and processing performance, is widely used in glass fiber reinforced plastic, artificial marble, man-made agate and other composite materials, and the oil industry, aerospace, new high-speed trains, cars, ships, heat insulation coatings, and other fields, effectively promote the role of the development of science and technology of China.
