Glass Fiber Tape

Application


Glass Fiber Tape is woven from texturized e-glass fiber yarn on specialized looms. GFT is suitable for temperatures upto 550oC, and typically used as high temperature gaskets between flanges or simply a wrap on pipelines to reduce heat loss in high heat generating areas.

GFT can be pre-inserted with SS 304 to improve its tensile strength at elevated temperatures and it can also be coated with vermiculite or silicon rubber to make it 100% non-permeable. This makes it suitable for application in expansion joints and food industry.

Base Material


Glass Fibre, which is used in weaving GFT is chemically known as boro-silico-alumino-calcic glass. It is a texturized e-glass yarn with a filament diameter of 9 micron.

It is chemically composed of the following:

SiO2 content (53-60%)

Al2O(11-15.5%)

Alkaline Terrous Oxides [CaO, MgO] (20-25%)

TiO(0-3%), B2O(0-9%)

Alkaline Oxides [Na2O, K2O] (<2%)
