ⅠIntroduction
Glass beads are made from borosilicate raw materials with high technology and its particle size is from 10 to 250 microns.It has the advantages of light weight, low heat conduction, high strength and good chemical stability.We generally use glass beads with particle size more than 1mm as toys filler. First of all, because of the glass beads light weight and high strength can give toys a better texture and plasticity. Secondly, the low thermal conductivity of glass beads and chemical stability make it more safe to be used as toys filling material, and not to worry that the filler material can cause harm to consumers. Again, with the development of modern production technology , our production of the glass beads is smooth, uniform size, wear-resisting stability, this will make more mature application in the field of toys filling.

Ⅲ Background
The current domestic plush toys fillers are mainly chemical fiber ingredients such as PP cotton material. In addition, there are using plastic and foam particles to fill toys, but few enterprises using the glass beads as the filling material.
PP cotton is a man-made chemical fiber composed of polypropylene, although it has a very fluffy and lightweight shape, but it has a poor flame retardancy and is prone to bacteria. So the finished product is likely to be carrying the harmful chemicals. Plastic particles are also due to the material and production process problems, so it has the same drawbacks as PP cotton, and it is difficult to let the consumers trust. As a vulnerable group, children need more attention and care. The choice of glass beads for stuffed toys makes us more confident to face consumers.
