Fiber Glass Reinforcement Mat
Fiber Glass Reinforcement Mat is a sheet reinforcing material made primarily of alkali-free glass fiber.
It is produced through chopping, random spreading, bonding or needling processes, and serves as a core substrate for FRP and composite materials.
It features light weight, high strength, excellent acid and alkali corrosion resistance and good electrical insulation. It achieves fast resin wetting and fits complex curved surfaces easily.
It is commonly available as chopped strand mat, continuous mat and needle mat, suitable for hand lay-up, compression molding and pultrusion processes. Widely used in industrial anti-corrosion projects, automotive parts, ship hulls, storage tanks & pipelines, wind turbine blades and sanitary ware, it provides structural reinforcement, toughness improvement, weight reduction and long-term durability.
- Product Introduction
Products Description
Fiber Glass Reinforcement Mat is a high-performance sealing gasket composite produced through a special glue impregnation process with fiberglass as the primary reinforcing material. This product integrates fiberglass's exceptional tensile strength and temperature resistance, with a softening temperature of 950°C, an ultimate tensile strength of 350 kg/mm², and an elastic modulus of 7300 kg/mm². It also delivers great flexibility and reliable sealing performance from its base substrate, making it ideal for flange sealing connections under diverse complex operating conditions.The product features a smooth surface and uniform thickness ranging from 5 mm to 25 mm. Its formula can be flexibly modified to satisfy different pressure classes and medium service requirements. The optimal storage environment maintains a temperature of 15°C to 35°C and relative humidity between 30% and 70%. It is extensively applied for sealing pipelines, valves and pressure vessels in chemical, power, petrochemical, pharmaceutical and other industrial sectors.
Product Advantages
High structural strength with superior compression and tensile performance; resistant to deformation and fracture in long-term service.
It possesses a broad high-low temperature resistance range and maintains stable sealing performance at operating temperatures up to 850°C.
Excellent chemical corrosion resistance, compatible with a variety of acid, alkali and organic solvent media.
Good compression and recovery performance, retaining reliable sealing after repeated disassembly and assembly for a long service life.
Application Scope
Widely used for static sealing at flange joints of chemical pipelines, reactors and storage tanks.
Suitable for high-temperature and high-pressure equipment sealing in power plant boilers, steam turbine units and heat exchangers.
Applied to flange sealing of petrochemical refining units, oil transmission pipelines, valves and pump bodies.
Applicable to pipelines in pharmaceutical, food and water treatment industries with strict hygiene and anti-corrosion requirements.
Process Technology
Adopts multi-layer cross-laid glass fiber for uniform reinforcement distribution without weak structural points.
Strictly controlled impregnation process ensures proper resin penetration and content, achieving full bonding between fiber and matrix.
High-temperature hot pressing and curing treatment deliver uniform density and minimal internal stress.
Precision surface finishing ensures high flatness, tight sealing surface fitting and zero leakage risk.
Functional Features
Excellent temperature and pressure resistance, maintaining stable performance under alternating temperature and high-pressure working conditions.
Moderate flexibility allows easy cutting and shaping, adaptable to non-standard flanges and special-shaped sealing surfaces.
Eco-friendly, non-toxic and asbestos-free, fully compliant with modern industrial safety and environmental regulations.
FAQ
Q: Can Fiber Glass Reinforcement Mat replace asbestos gaskets?
A: Yes, it is eco-friendly, non-toxic and asbestos-free, with better sealing performance and longer service life than traditional asbestos gaskets.
Q: What is the maximum temperature resistance?
A: Depending on different formulas and reinforcement structures, it covers low, medium and high temperature ranges. Please contact us for professional selection.
Q: Can non-standard sizes and special shapes be customized?
A: Customization is available. We can produce various special-shaped gaskets according to your flange specifications or drawings.
Q: Does it require special treatment before installation?
A: Generally no special treatment is needed, and it can be installed directly. For special medium conditions, compatibility confirmation is recommended in advance.
Operating Instructions
1
Standard packaging uses woven bags mounted on pallets, whereas special-shaped cuttings are packed in cartons. Thoroughly clean flange sealing surfaces prior to installation to remove scratches, rust and residual fragments of old gaskets.
2
Standard roll widths of the mat are 1.2 m and 1.5 m, and the material can be cut to custom dimensions. Position the cut mat centrally between the flanges, and tighten all bolts evenly in a diagonal cross pattern to stop leakage triggered by uneven compressive stress.
3
For initial start-up, run the equipment at a working temperature no higher than 850°C for a period, then inspect for bolt loosening and retighten fasteners as needed.
4
Store the product in a cool, dry area with ambient temperature kept at 15°C–35°C and relative humidity of 30%–70%. Keep away from direct sunlight and humid surroundings.
