Expanded Graphite with Stainless Foil Insert 500 mm length X 500mm Width X 1.5mm Thick

Key Features

Polymax GP550, a premium sealing solution expertly Made from expanded natural graphite with over 99% purity. This advanced material incorporates a stainless steel foil insert (AISI 316; 0.05 mm), providing exceptional mechanical strength and durability. Designed to meet the demanding needs of various industrial applications, Polymax GP550 ensures long-lasting performance and reliability.

Polymax GP550 holds BAM (oxygen) approval, confirming its safety for use in oxygen-enriched environments. This certification guarantees compliance with stringent industry standards, making it an ideal choice for users prioritising safety and reliability in their operations.

With a density of 1.3 g/cm³ (as per DIN 28090-2) and a low total sulfur and leachable chloride and fluoride content (20 ppm each), Polymax GP550 ensures unparalleled purity. Its less than 1% ash content further enhances its suitability for sensitive applications where contamination must be avoided.

Experience outstanding physical properties with Polymax GP550, featuring a remarkable 42% compressibility rate and a 15% recovery rate. This ensures tight sealing and extends the lifespan of your applications. The material exhibits substantial tensile strength, able to withstand residual stress up to 49 MPa, even after prolonged exposure to high temperatures.

Polymax GP550 maintains a specific leak rate of only 0.05 mg/(s·m) and showcases significant compression and creep relaxation properties. This ensures reliability and stability, even under extreme stress and temperature variations, making it a top choice for a wide range of industrial applications.

Applications

Polymax GP550 is engineered for extreme environments, capable of operating at temperatures ranging from -200°C (-328°F) to 550°C (1022°F) in oxidising atmospheres, and up to 700°C (1292°F) in reducing or inert atmospheres. With a maximum pressure capacity of 100 bar (1450 psi), it is particularly well-suited for high-stress applications in the chemical and petrochemical industries.

This versatile sealing solution is ideal for applications in oil and gas, power generation, and various manufacturing processes, ensuring optimal performance and longevity. Whether you require reliable seals in high-temperature environments or seek materials that comply with rigorous safety standards, Polymax GP550 stands out as the superior choice.
