The glass fiber tape is made of high-temperature resistance and high-strength glass fiber, which is processed by special process . It has the characteristics of high temperature resistance, heat insulation, insulation, fire retardant, corrosion resistance, aging resistance, weather fastness, high strength and smooth appearance .It is one of the reinforcement technical fabric.
Product application: Glass fiber tape is mainly used in industry: heat insulation, fireproof, inflaming retarding, seal, etc. Especially, it is applied to the sealing and protection of all kinds of household fireplaces .
Technical Overview:
Size Range:
Width: 15-300 mm
Thickness: 1.5-5mm
Standard length: 30M
The process of transforming melted glass into fibers through heating and drawing glass into fine fibers has been known for millennia; however, only afer the industrial development during the 1930s have made possible a mass producton of these products suitable for the textile applicatons.
The fibers are obtained through a five step process known as batching, melting, fiberizaton, coating and drying/packaging.
•Batching
During this step, the raw materials are carefully weighed in exact quantities and thoroughly mixed or batched. For example, E-Glass, is composed by SiO2 (Silica), Al2O3(aluminium oxide), CaO (Calcium oxide or lime), MgO (magnesium oxide), B2O3 (boron oxide), etc…
•Melting
Once the material is batched is then sent to special furnaces with a temperature of about 1400°C . Normally furnaces are divided into three sectons with different temperature range.
