Adding hollow glass microbeads to the resin will change many of its physical properties. The following briefly introduces several physical characteristics that will change after adding hollow glass microbeads to the resin: good fluidity and excellent product size stability. Since hollow glass microspheres are tiny round balls, they behave like miniature ball bearings in liquids, and have better fluidity than filled particles in the form of flakes, needles or irregular shapes. The resulting microsphere effect, The viscosity of the mixture is reduced, the filling performance is naturally excellent, and the good processing performance can increase the production efficiency by 15% to 20%.



Since the spherical object is isotropic, the filling beads will not cause the inconsistency of shrinkage of different parts due to the orientation, which ensures the stable size of the product and does not warp, which solves the molding of profiled materials and large injection products Long-term deformation problems in processing.

Low thermal insulation, sound insulation, insulation and water absorption. The inside of the hollow glass microbeads is inert gas. The density and thermal conductivity of the two different materials are poor. Therefore, it has the characteristics of sound insulation, heat insulation and low thermal conductivity. It is an excellent filler for various thermal insulation and sound insulation products. The thermal insulation properties of the microbeads can also be used to protect the product from thermal shock caused by alternating changes between rapid heating and rapid cooling conditions. Very high specific resistance and extremely low water absorption rate make it widely used in processing and production of cable insulation materials.

Low oil absorption rate. Compared with the conventional filler calcium carbonate, the absorption rate of hollow glass microspheres is much lower. The oil absorption rate per 100 grams of different types of products is between 7 and 50 mg, while the oil absorption rate per 100 grams of light calcium carbonate Up to 120 to 130 mg, and heavy calcium carbonate up to 50 to 60 mg. During the production process, this low oil absorption filler material not only reduces the amount of plasticizer, but also increases the filler amount in disguise and reduces the overall cost.
