What is hollow glass bead? Hollow glass microsphere is a new light material of micron-scale developed in the 1950s and 1960s. Its main component is borosilicate, and its particle size is generally 10-250 μ m. The wall thickness is 1-2 μ m; Hollow glass beads are characterized by high compressive strength, high melting point, high resistivity, low thermal conductivity and thermal shrinkage coefficient. They are known as the "materials of the space age" in the 21st century. Hollow glass beads have obvious weight reduction and sound insulation effects, making products have good crack resistance and reprocessing performance. They are widely used in engineering plastics, anti-corrosion and thermal insulation materials, rubber, buoyancy materials, glass fibre reinforced plastics, artificial marble, artificial agate, Daimu and other composite materials, as well as petroleum industry, aerospace, 5G communications, new high-speed trains, automobiles and ships, thermal insulation coatings, adhesives and other fields.
Characteristics of Hollow Glass Beads Pure white colour: it can be widely used in any product with requirements for appearance colour. Light specific gravity: the density of hollow glass beads is about one-tenth of the particle density of traditional filler, which can greatly reduce the base weight of the product after filling, replace and save more production resins, and reduce the product cost. Oiliness: hollow glass bead is easily wetted and dispersed and can be filled in most thermosetting thermoplastic resins, such as polyester, epoxy resin, Polyurethane, etc. Good fluidity: because hollow glass beads are small round balls, they have better fluidity in liquid resin than fillings of sheet, needle or irregular shape, so they have excellent filling performance. More importantly, these beads are isotropic, so they will not have the disadvantage of inconsistent shrinkage of different parts. They ensure the product's dimensional stability, with No warping. Heat insulation and sound insulation: the interior of a hollow glass bead is thin gas, so it has the characteristics of sound insulation and heat insulation. It is an excellent filler for various heat insulation and sound insulation products. The heat insulation characteristics of hollow glass beads can also protect products from the thermal shock caused by the alternating changes between hot and cold conditions.
Application fields of hollow glass beads It is widely used in FRP products, composite foam plastics, artificial marble, synthetic wood, sound insulation materials, putty, deep-sea buoyancy materials, bowling balls, low-density adhesives, sealing materials, lightweight resin crafts, mural wall hanging frames, sandwich layer structure of wallboards, electronic industry lightweight packaging materials, wave absorbing materials, lightweight concrete, emulsion explosives, etc. Artificial marble: hollow glass beads are widely used in artificial marble. In the United States, Many manufacturers are using this filler, which has the following advantages: ① improves the impact performance, and the performance of products manufactured with the correct formula is higher than the requirements of the Artificial Marble Association. ② Improve the texture layout and colour continuity to make the product more beautiful and dazzling. ③ Reduce the curing time, have a faster mould turnover speed, ④ improve the impact strength, improve the anti-cracking ability, and reduce the damage rate of products. ⑤ Improve machinability and reduce deburring, cutting, drilling and grinding time.
Price of hollow glass bead Hollow glass bead particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of hollow glass bead. A large amount of large amount will be lower. The Price of hollow glass bead can be found on our company's official website.
