The composition characteristics of hollow glass beads: Fengcai Beads Factory Composition Soda lime silicate has pure white color and can be widely used in any products that require appearance and color. The density of hollow glass beads with light specific gravity and large volume is about one tenth of the density of traditional filler particles. After filling, it can greatly reduce the basis weight of the product, replace and save more production resins, and reduce product costs. Hollow glass beads with an organically modified (lipophilic) surface are easy to wet and disperse, and can be filled in most thermosetting thermoplastic resins, such as polyester, epoxy resin, polyurethane, etc. High dispersion and good fluidity. Because hollow glass beads are tiny spheres, they have better fluidity in liquid resin than flake, needle or irregularly shaped fillers, so they have excellent mold filling performance. What's more important is that this kind of small microbeads are isotropic, so there will be no inconsistencies in the shrinkage of different parts due to orientation, and the dimensional stability of the product is guaranteed without warping. Heat insulation, sound insulation, insulation, low water absorption The inside of hollow glass microspheres is 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 the product from the thermal shock caused by the alternation between rapid heating and rapid cooling conditions. High specific resistance and extremely low water absorption make it widely used in the processing and production of cable insulation materials. The particles of the low oil absorption sphere determine its smallest specific surface area and low oil absorption. The amount of resin can be greatly reduced during use, and the viscosity will not increase much even under the premise of high addition, which greatly improves the production operation Conditions can increase production efficiency by 10% to 20%.
