Melting point is 680 ℃The boiling point of 1000 ℃Density of 2.4 ~ 2.7 g/cm3 Glass fiber as reinforcement of reinforced plastic materials, the biggest characteristic is tensile strength.Tensile strength under standard condition is 6.3 ~ 6.9 g/d, moist condition 5.4 ~ 5.8 g/d.The density of 2.54.Good

The main composition of silica, alumina and boron oxide and magnesium oxide, calcium oxide, sodium oxide, etc., according to the amount of alkali content, in the glass can be divided into non-alkali glass fiber (0% ~ 2% sodium oxide, aluminum borosilicate glass), the alkali glass fiber (8% ~ 12% sod

English names：fiberglass,glass fiberEnglish nickname：Glass cotton,fiber glass, fiber,calcium,boron aluminum silicate glass microspheres.

What is the fiberglass?Fiberglass is an excellent inorganic non-metal material, variety, advantage is that by good insulation, heat resistance, good corrosion resistance, high mechanical strength, but the drawback is crisp, poor wear resistance.
