Product Description

Product Description

Glass bead is a new kind of material developed in recent years, which is widely used and has special properties. The product is made of borosilicate raw materials through high-tech processing, with particle size of 10-250 μ m and wall thickness of 1-2 μ M.

The product has the advantages of light weight, low thermal conductivity, high strength, good chemical stability and so on. The surface of the product is treated with special treatment, which is oil-friendly and hydrophobic. It is very easy to disperse in the organic material system.
