Hollow glass microspheres are tiny, lightweight spheres made of glass that are used in a variety of applications. Due to their unique properties, hollow glass microspheres are being used in many industries such as aerospace, automotive, construction, defense, and energy. Some of the applied-technologies of HGMs are:
Lightweight fillers: hollow glass microspheres are used as a lightweight filler in many materials such as plastics, resins, and composites. By adding HGMs, the weight of the material can be reduced, while maintaining its strength and durability.
Thermal insulation: hollow glass microspheres have a low thermal conductivity, making them an excellent choice for thermal insulation materials. HGMs are used in a variety of insulation products, including spray foams, rigid boards, and blankets.
Buoyancy and flotation: hollow glass microspheres are used in buoyancy and flotation devices, including buoys, life jackets, and floats. HGMs can provide buoyancy while also reducing the weight of the device.
Acoustic insulation: hollow glass microspheres are used as an acoustic insulation material in many applications such as automotive parts, building insulation, and sound barriers. HGMs can absorb sound waves and reduce noise transmission.
Cosmetics: hollow glass microspheres are used in cosmetics and personal care products as a light-scattering agent. HGMs can provide a soft-focus effect, reduce the appearance of wrinkles, and give a silky texture to the skin.
Oil and gas drilling: hollow glass microspheres are used in oil and gas drilling fluids to reduce the density of the fluid and increase its flow rate. This can help to improve drilling efficiency and reduce costs.
