Type of Glass Fiber yarn
Glass Fiber Yarn
Glass Fiber is a material made by 5 - 13microns diameter non-organic fiber which is made
by melting the mixed refined glass raw materials at high temperature at 1200-1500℃.
Glass Fiber yarn is used with two tyes of single yarn and plied yarn according to its usage.

Glass Fiber Texurized Yarn & Glass Roving
Glass Fiber texturized yarn is made by glass fiber yarn with texturized machine. And, it is
used in manufacturing insulation fabric and filter bag by using its heat insulation and
filtering property. Glass roving is used for strength reinforcement of FRP such as vessel
and septic tank.

Property of Glass Fiber Fabrics
KGF glass fiber fabrics are mostly fabricated by "E"glass yarn and glass fiber fabric is designed and supplied to the customers according to the requirement of the customers.
Type of construction
Mechanical Property
| High tensile strength |
Glass fiber is one of the fibers that have the highest tensile strength. Its weight is lighter than that of steel wire but its tensile strength is stronger than that of steel wire |
| Good dimensional stability |
Glass fabrics has low elongation percentage(below 3%) and so has excellent dimensional stability |
| High heat resistance |
Glass fiber fabric is applied in high temperature working conditions with relatively cheaper investment. Glass fabric can stand about 50% tensile strength at 700℉(371℃) and about 25% at 482 ℃. Softening point is 846℃ and melting point is 1121℃ |
| Incombustibility |
Glass fiber fabric made of inorganic materials are noninflammable fabric and applied to especially in the dangerous places of fire. |
| High thermal condutivity |
Glass fiber fabric emit heat more rapidly and suitable for insulation |
| chemical resistance |
Like glass itself, glass fiber fabric is highly resistant to attrack by most chemicals |
| Electric insulation |
Excellent heat resistance property and low hygroscopic. And, has a superior electric insulation which is applied to the fields of electric industry |
| Endurance |
Safe from sunlight, dust fungi & bacteria |
| Economic |
Economical material comparing with other similar fabrics |

Heat treatment & Coatings
Glass fiber fabric is possible to use without treatment and also widely used according to those specific usage with suitable treatments or coatings such as heat treatment, silane finish, prepreg, coating and laminating.
Heat Treatment
In order to enhance the compatibility on twisting / weaving, binders such as oil, agent is used when fiber forming and beam sizing.. Heat treatment process remove various binders according to the application.
Silane Finish
It is surface treatment on fabrics with coupling agents compatitable with several resins.
Prepreg
To make a cloth, undergoes heat cleaning and coupling agent process, into a semi-cured condition by soaking it in the mixture with an appropriate hardner. resins such as epoxy resin, phenol resin, unsaturated polyester and others by a certain ratio
Coating
It is surface treatment with acrylic resin, silicone resin, urethane resin or other special resin according to the application
Laminating
It is binding process with glass fiber fabric and aluminium foil sheet, film or paper.
