Product Description

High performance Hollow glass microspheres size 10-120μm density reducing ​


Description of hollow glass microspheres:


High-performance hollow glass beads (hereinafter referred to as HGS) is a closed, hollow sphere with a wall thickness of 1~3μm, containing dilute nitrogen, carbon dioxide and other gases. Its main chemical composition is soda lime borosilicate glass. HGS, as a lightweight micron-level resin material filler, can effectively reduce the density of products, increase or improve the water resistance, mechanical properties, shrinkage and rheological properties of products.

Properties of hollow glass microspheres:



1. Good economy


Compared with fillers of other shapes, hollow glass beads have a small surface area to volume ratio and low oil absorption, which can reduce the amount of matrix resin and increase the amount of fillers. At the same time, glass beads with a smaller volume can be filled into larger gaps of glass beads, increasing the total filling amount, further reducing the amount of resin, and reducing the cost. Lightweight glass hollow microspheres can occupy more volume than ordinary fillers of the same weight. This means that hollow glass microspheres have more cost advantages when considering unit volume cost rather than unit weight cost.


2. Reduce viscosity and increase fluidity


The appearance of hollow glass microspheres is spherical. Compared with other irregular-shaped fillers, it is easier to flow and can roll like steel balls in a bearing. Therefore, adding hollow glass microspheres to the composite material can reduce the melt viscosity and The internal stress makes the processing and forming easier, which is conducive to the conventional forming of composite materials.


3. Reduce material density


Generally, fillers have a relatively high density and are added to plastics and rubbers as extenders. Although they can achieve the purpose of reducing costs, they tend to increase the density of the products and affect the performance and use of the products. Because hollow glass beads are hollow products, especially floating beads, the density is very small, about 0.40 ~ 0.75 g/cm3. Now some products, such as some hollow glass beads of 3M company, have a lower density, which can reach 0.125~0.16. g/cm3 level. Adding such low-density fillers to plastics can not only reduce costs, but also make products lighter.
