What yarn is used for fiberglass cloth?

Generally made of E-glass/C-glass with filament diameters ranging from 6 to 11 um.

What's your width of fiberglass cloth ?

Our standard width is 1000mm , 1270mm. 25"/27"/30".Customized width available too.

What is the warp and weft density of fiberglass cloth? Can it be adjusted?

Yes, we can adjust the warp and weft density of fiberglass cloth according to the customer's requirements for strength/surface effect, etc.

What are the properties of fine fiberglass cloth?

Fiberglass cloth features excellent waterproof and moisture-proof performance. It also resists acid, alkali, oil and weather aging with great chemical stability. When combined with resins, it forms a durable protective layer suitable for outdoor and corrosive environments.

Do you produce the yarn for your fiberglass cloth in-house?

We also produce the yarn ourselves. It features stable quality, high output and low cost.

What kind of fiberglass cloth do you usually choose for surfboards?

Specification: 4OZ, 5OZ, 6OZ, 7 OZ. Width:25'' 27'' 30'' 38''

Can you adjust the thickness of the fiberglass cloth?

Yes, we can adjust the yarn diameter and warp and weft density to meet your requirements.

Key features

Lightweight & flexible: Fiberglass cloth is thin and soft with excellent conformability. It easily fits complex curved and irregular surfaces for easy application.

High mechanical strength Fiberglass cloth features great tensile strength and toughness. It effectively reinforces structures and offers good flex resistance.

Superior electrical insulation: Fiberglass cloth is made of E-glass. It has stable dielectric properties and high voltage resistance, making it ideal for electrical insulation and CCL production.

Heat resistance & dimensional stability Fiberglass cloth withstands high temperatures with minimal thermal deformation. It maintains stable dimensions under varying temperatures.

Good chemical & weather resistance: Fiberglass cloth resists acid, alkali, oil and aging. It is also waterproof and moisture-proof for anti-corrosion and outdoor use.

Fiberglass cloth has a uniform yarn structure. It allows fast and thorough impregnation with epoxy, polyester, vinyl ester and other resins to form integrated finished products.

Cost-effective: Fiberglass cloth consumes less resin than heavy fiberglass cloth. It helps reduce overall production costs.

Wide Application:Fiberglass cloth is widely used in electronics, FRP products, waterproofing, anti-corrosion, transportation, recreational goods, fire protection and thermal insulation.

Wide range of area weight: Fiberglass cloth regular area weight is 30g, 50g, 80g, 100g, 160g, 200g, 240g, 300g, 320g, and 400g. Other weight could also be customized.

Fiberglass cloth are made of silane yarn. The specially designed sizing reduces broken filaments and debris during weaving, ensuring smoother operation and a cleaner, more defect-free surface.
