Hollow Glass Microspheres

1) Introduction

Hollow glass microsphere is a new type of material which has wide use and an outstanding performance. The product is made mainly from borosilicate, it is a hollow and grain size is 8-130 micron.

The product has many advantages: substantial weight saving, low heat conductivity, high mechanical strength and fine chemical stability. It has the properties of lipophilicity and hydrophobicity. It is easily dispersed in organic materials such as resin.

Hollow glass beads are widely used in the composite materials such as FRP (fiber reinforced plastics), man-made marble and man-made agate. They have the distinct results of decreasing weight, sound insulation and heat preservation, thus the products have the excellent performances of anti-crazing and re-processing. They are widely used in a range of fields such as: Man-made marble, heat insulation Coating, Putty powder, Plugging agent, Adhensive agent, spray-painted material, PU injecting plastic, Foam, FRP products, Floating material, Polyester Casting Furniture, Fluid for drilling, Lightweight Cement, Bowling, Golf and ect.
