Glass beads BS6088A BS6088B road-reflect abrasive
1 Description
Glass bead is made of high quality material production and become, has certain mechanical strength, have enough flexibility, can be used multiple times is not easy and broken, the spray device, obvious effect, not hurting objects’ surface, long service life than ordinary glass bead more than 3 times, good evenness, round rate is greater than 98%, granularity and the bubble content is very low.
The glass beads, composed of SiO2,Na2O and CaO, are broken and calcined by high temperature after which the said microspheres are obtained. With properties of the high roundness rate, better hardness, excellent anti-friction and direct reflect light ,etc, they are widely applied in the fields of plastic rubber, abrasion ground, blast derusting , road-reflect dope and handicraft lamp, etc
