FRP (Fiber Reinforced Polymer) Mesh Tape is a specialized reinforcement tape designed to strengthen, repair, and reinforce surfaces in a variety of industrial, commercial, and residential applications. Made from high-strength fiberglass and coated with a durable polymer resin, FRP mesh tape combines the superior tensile strength of fiberglass with the versatility and chemical resistance of polymer resins. This tape is widely used for patching, repairing, and reinforcing cracks, joints, and seams in a range of materials such as concrete, drywall, fiberglass, and metal.

Key Features of FRP Mesh Tape

1. High Strength:
   The fiberglass mesh used in FRP mesh tape provides exceptional strength, making it resistant to tears, stretching, and damage. This high tensile strength ensures that the tape can effectively reinforce surfaces and provide long-term durability.

2. Flexibility:
   The tape is flexible enough to conform to uneven or curved surfaces, ensuring that it can be used in a variety of applications, from flat walls to corners, joints, and pipes.

3. Chemical Resistance:
   The polymer resin coating on the fiberglass mesh provides resistance to common chemicals, oils, and solvents, making it ideal for use in industrial and manufacturing environments where exposure to harsh substances is frequent.

4. Moisture Resistance:
   FRP mesh tape is resistant to water and moisture, which makes it ideal for use in wet or humid environments such as plumbing, marine, and roofing applications.

5. UV Resistance:
   FRP mesh tape with UV inhibitors prevents degradation from prolonged exposure to sunlight, ensuring that the tape maintains its strength and flexibility even in outdoor or sun-exposed areas.

6. Non-Rusting:
   Unlike metal reinforcement materials, FRP mesh tape is non-corrosive and will not rust, making it suitable for applications in environments that are exposed to moisture and humidity.

7. Ease of Installation:
   FRP mesh tape is lightweight, easy to handle, and can be quickly applied. It is also easy to cut to size, making it a convenient option for both DIY projects and professional contractors.

Specifications of FRP Mesh Tape

1. Material Composition:

   • Fiberglass Mesh: The core material of the tape is a woven fiberglass mesh, which is known for its strength, durability, and ability to handle high stresses without tearing.
   • Polymer Resin Coating: The fiberglass mesh is coated with a polymer resin, such as epoxy, polyester, or vinyl ester, to enhance adhesion, chemical resistance, and UV stability.

2. Dimensions:

   • Width: FRP mesh tape is available in various widths, typically ranging from 2 inches (50 mm) to 6 inches (150 mm). Custom widths can also be made depending on the application requirements.
   • Length: The length of FRP mesh tape typically ranges from 50 feet (15 meters) to 500 feet (150 meters) per roll, with some manufacturers offering bulk packaging for large-scale applications.
   • Thickness: The thickness of the tape typically varies from 0.2 mm to 0.5 mm, depending on the intended use. Thicker tapes are more suitable for heavy-duty applications, while thinner versions are ideal for light repairs.

3. Weight:
   The weight of FRP mesh tape varies depending on the width, length, and resin coating. On average, it weighs approximately 0.2 to 0.4 lbs (90 to 180 grams) per roll, but this can vary based on the size and material composition.

4. Tensile Strength:

   • Average Tensile Strength: The tensile strength of the fiberglass mesh used in FRP mesh tape is typically in the range of 350 to 500 MPa (MegaPascals), making it highly resistant to stretching and tearing under stress.
   • Breaking Strength: The breaking strength of the tape depends on the type of resin and fiberglass used, with some tapes able to withstand forces up to 1,000 lbs (450 kg).

5. Adhesion Strength:
   FRP mesh tape exhibits excellent adhesion to various surfaces, including concrete, drywall, metal, and fiberglass. The adhesive strength of the tape ensures it stays in place even in high-stress areas, providing long-term reinforcement.

6. Chemical Resistance:

   • Resistance to Solvents: FRP mesh tape resists many common solvents, oils, and chemicals, including gasoline, diesel fuel, and harsh industrial chemicals. The exact resistance may depend on the type of polymer resin used in the coating.
   • Resistance to Acid and Alkali: The tape shows good resistance to both acidic and alkaline substances, making it suitable for use in chemical plants, laboratories, and other industrial applications.

7. Temperature Resistance:

   • Operating Temperature Range: FRP mesh tape can typically withstand temperatures between -40°F (-40°C) to 250°F (121°C), depending on the specific type of resin used. This allows the tape to perform in a wide range of environments, from cold storage to high-temperature industrial settings.
   • Melting Point: The polymer resin coating generally has a melting point around 250°F to 350°F (121°C to 177°C), although this can vary based on the type of resin used.

8. UV Resistance:
   Many FRP mesh tapes are designed with UV inhibitors to prevent degradation from prolonged exposure to sunlight. This makes them ideal for use in outdoor applications such as roofing, siding, and other exposed surfaces.
