Magic Custom-built Glass Bubbles

To meet customer’s demand, a variety of  hollow glass microspheres with different particle size, density and intensity are made. It can help customers to improve the performance and quality of their finished product, ensuring a smooth and trouble-free production process at a lower cost.

Unique performance

High-performance hollow glass bead is a kind of ultra-lightweight inorganic non-metallic powder with hollow microsphere, and it is a versatile and high-performance new lightweight material developed in recent years. It will be the new composite mainstream materials at twenty-first century. Its true density is 0.15-0.60g/cm3 with 2-130μm in diameter. It owns features with light weight, large bulky, low thermal conductivity, high compressive strength, smoothly mobility.
It can be used in paint and coatings, rubber, plastics, glass, steel, artificial stone, putty and other products as filler and weight-reducing agent.
Because of its high compressive properties, it can be used to produce high-strength low-density cement slurry and low-density drilling fluid in oil and gas extraction industry.

Why should we choose high-performance hollow glass beads?

1.Improve flow properties.

Hollow glass microsphere is a tiny sphere with high ball-type rate. Its ball-bearing effect can improve its mobility and reduce the viscosity and internal stress of resin mixture. Therefore,during processing, less heat is produced in composite materials so as to prevent inadequate lubrication and partial thermal decomposition. It is more likely to extrude when molding, which can not only reduce defects in products, but also improve the production efficiency by 15% -20%.

2.A superior substitute of resin.

Hollow glass microspheres occupy less surface area, low oil-absorption rate, and evenly disperse in mixture. Its easy compression and integration permit high filler loadings. It significantly reduces the consumption of resins, increases the amount of filler, and effectively reduces VOC indicators, and costs as well.

3.Low shrinkage and warpage.

Hollow glass microspheres have the feature of isotropism and high-filling, hence the dimensional stability of the product will be very high and it will reduce the shrinkage and warpage. With an appropriate filling ratio, the toughness of the products, impact-resistance and surface hardness can be significantly improved.

4.More economical.

The density of high-performance hollow glass microspheres is only a fraction of that of the resin. A small amount of hollow glass microspheres will be able to replace heavier materials. When considering the cost per unit volume, rather than cost per unit weight, high-performance hollow glass microspheres can significantly reduce costs.

5.Adjusting product density

The density of hollow glass microspheres is usually 0.20 ~ 0.60g/cm3, and the density of mineral filler is generally around 2.7 ~ 4.4 g/cm3 (The data adopted is the true particle density). In order to obtain the equal size, 14 kilograms or more of talc must be used to obtain the same effect of 1 kg of hollow glass microsphere. Hence the desired ideal density can be obtained by adding appropriate proportions of hollow glass microspheres.
