Glass Tube (GT002)

Product Description

Our company mainiy produces series of borosilicate glass product in various colors, rods and tubes in different sizes. The main featuer of our product is that it has the minimum expansion coefficient(a=3.3*10-6), stable resistance to heat and cold, good perfomance against the sudden temperature change(270º C), fine chemical stability(the water and alkali resistance reach the Grade A). This product has excellent property for making lamp oenaments and is noted by its antidecoloring, antiexplosion and antiexplosion. The products we are making are widely used for making various light decorations, utensils, ornaments and top-grade crafts.
