High Strength and Durability of G10 Isolation Gasket
The high strength and durability of the G10 Isolation Gasket are among its core advantages, making it excel in extreme industrial environments.

1. High-Density Structure and Mechanical Properties
The G10 Isolation Gasket is made from G10 material, a composite formed by laminating fiberglass cloth and epoxy resin under high temperature and pressure. Its high-density structure grants it exceptional mechanical properties:
Compressive Strength: G10 offers a compressive strength of up to 310 MPa, far exceeding that of ordinary plastics or rubber, enabling it to withstand extremely high pressures without deformation or rupture.

Tensile Strength: With a tensile strength of 480 MPa, the G10 Isolation Gasket maintains high strength and stability even under tensile stress.

Flexural Strength: G10’s flexural strength is approximately 400 MPa, indicating its ability to maintain structural integrity under bending stress.

Elastic Modulus: G10’s elastic modulus is around 21 GPa, demonstrating high stiffness and effective resistance to deformation caused by external stress.

2. High-Temperature Tolerance
The G10 Isolation Gasket exhibits excellent stability in high-temperature environments:
Continuous Operating Temperature: G10 can maintain stable performance at continuous operating temperatures of up to 180°C without softening or degradation.

Short-Term Tolerance: For short durations, G10 can tolerate temperatures as high as 200°C, making it suitable for high-temperature industrial applications.

Thermal Expansion Coefficient: G10’s low thermal expansion coefficient of 12×10⁻⁶/°C ensures minimal dimensional changes during temperature fluctuations, making it ideal for precision equipment and high-pressure sealing applications.

3. High-Pressure Tolerance
The G10 Isolation Gasket performs exceptionally well in high-pressure environments:
Pressure Resistance: G10 can withstand pressures of up to 1500 psi (pounds per square inch), making it suitable for sealing and isolation in high-pressure pipelines, valves, and vessels.

Impact Resistance: G10’s impact strength of approximately 100 kJ/m² allows it to withstand sudden mechanical shocks without fracturing.

4. Chemical Resistance and Low Moisture Absorption
The G10 Isolation Gasket excels in chemically corrosive and humid environments:
Chemical Resistance: G10 demonstrates excellent resistance to most acids, alkalis, solvents, and oils, ensuring long-term stability in corrosive media.

Low Moisture Absorption: With a moisture absorption rate of less than 0.1%, G10 maintains its performance even in humid environments, ensuring long-term durability.

The G10 Isolation Gasket, with its high-density structure, exceptional mechanical properties, high-temperature and high-pressure tolerance, as well as chemical resistance and low moisture absorption, is an ideal choice for demanding industrial environments. Its performance metrics, backed by professional data, ensure long-term reliability and safety in high-pressure, high-temperature, and corrosive conditions, significantly extending equipment lifespan and reducing maintenance costs. Whether in the oil and gas industry or power and chemical sectors, the G10 Isolation Gasket is the optimal solution for enhancing system safety and
